-This guide helps you migrate from the external validation system to the new built-in validation. - -## What Changed - -The GFQL validation system has been integrated directly into the AST classes, providing: -- Automatic validation during construction -- Structured error codes for programmatic handling -- Better performance with pre-execution validation -- More helpful error messages with suggestions - -## Migration Overview - -### Old System (External Validation) -```python -from graphistry.compute.gfql.validate import validate_syntax, validate_schema - -# Manual validation -issues = validate_syntax(query) -if issues: - for issue in issues: - print(f"{issue.level}: {issue.message}") -``` - -### New System (Built-in Validation) -```python -from graphistry.compute.chain import Chain -from graphistry.compute.exceptions import GFQLValidationError - -# Automatic validation -try: - chain = Chain(query) # Validates automatically -except GFQLValidationError as e: - print(f"[{e.code}] {e.message}") -``` - -## Key Differences - -### 1. Automatic vs Manual Validation - -**Before:** -```python -# Create query -query = [{"type": "n"}, {"type": "e_forward", "hops": -1}] - -# Manually validate -issues = validate_syntax(query) -if issues: - # Handle errors -``` - -**After:** -```python -# Validation happens automatically -try: - chain = Chain([n(), e_forward(hops=-1)]) -except GFQLTypeError as e: - print(f"Error: {e.message}") # "hops must be a positive integer" -``` - -### 2. Error Structure - -**Before:** -```python -class ValidationIssue: - level: str # 'error' or 'warning' - message: str - operation_index: Optional[int] - field: Optional[str] - suggestion: Optional[str] -``` - -**After:** -```python -class GFQLValidationError(Exception): - code: str # e.g., "E301" - message: str - context: dict # Contains field, value, suggestion, etc. -``` - -### 3. Error Types - -**Before:** Single `ValidationIssue` class with `level` field - -**After:** Specific exception types: -- `GFQLSyntaxError` (E1xx): Structural issues -- `GFQLTypeError` (E2xx): Type mismatches -- `GFQLSchemaError` (E3xx): Data-related issues - -### 4. Schema Validation - -**Before:** -```python -schema = extract_schema_from_dataframes(nodes_df, edges_df) -issues = validate_schema(query, schema) -``` - -**After:** -```python -# Runtime validation (automatic) -result = g.chain(query) # Raises GFQLSchemaError if invalid - -# Pre-execution validation (optional) -result = g.chain(query, validate_schema=True) -``` - -## Migration Steps - -### Step 1: Update Imports - -Replace old imports: -```python -# Remove these -from graphistry.compute.gfql.validate import ( - validate_syntax, - validate_schema, - validate_query, - ValidationIssue -) - -# Add these -from graphistry.compute.exceptions import ( - GFQLValidationError, - GFQLSyntaxError, - GFQLTypeError, - GFQLSchemaError, - ErrorCode -) -``` - -### Step 2: Remove Manual Validation Calls - -Old pattern: -```python -def process_query(query): - # Validate first - issues = validate_syntax(query) - if issues: - return None, issues - - # Then execute - chain = Chain(query) - return chain, None -``` - -New pattern: -```python -def process_query(query): - try: - chain = Chain(query) # Validation included - return chain - except GFQLValidationError as e: - # Handle error - raise -``` - -### Step 3: Update Error Handling - -Old pattern: -```python -issues = validate_query(query, nodes_df, edges_df) -for issue in issues: - if issue.level == 'error': - logger.error(f"{issue.message}") - else: - logger.warning(f"{issue.message}") -``` - -New pattern: -```python -try: - result = g.chain(query) -except GFQLSyntaxError as e: - logger.error(f"Syntax error [{e.code}]: {e.message}") -except GFQLSchemaError as e: - logger.error(f"Schema error [{e.code}]: {e.message}") - if e.code == ErrorCode.E301: - logger.info(f"Available columns: {e.context.get('suggestion')}") -``` - -### Step 4: Use Error Codes - -Error codes enable programmatic handling: - -```python -try: - result = g.chain(query) -except GFQLSchemaError as e: - if e.code == ErrorCode.E301: # Column not found - # Suggest available columns - print(e.context.get('suggestion')) - elif e.code == ErrorCode.E302: # Type mismatch - # Show type information - print(f"Column type: {e.context.get('column_type')}") -``` - -### Step 5: Leverage Collect-All Mode - -New feature for getting all errors at once: - -```python -# Get all validation errors -chain = Chain(query) -errors = chain.validate(collect_all=True) - -for error in errors: - print(f"[{error.code}] {error.message}") -``` - -## Common Patterns - -### Pattern 1: Query Builder with Validation - -```python -class QueryBuilder: - def __init__(self): - self.operations = [] - - def add_operation(self, op): - # Test validates immediately - test_chain = Chain(self.operations + [op]) - self.operations.append(op) - return self - - def build(self): - return Chain(self.operations) -``` - -### Pattern 2: Pre-execution Validation - -```python -def safe_execute(g, operations): - # Validate before expensive execution - chain = Chain(operations) - - # Pre-validate schema - if hasattr(chain, 'validate_schema'): - errors = chain.validate_schema(g, collect_all=True) - if errors: - logger.warning(f"Found {len(errors)} schema issues") - - # Execute - return g.chain(operations) -``` - -### Pattern 3: Error Recovery - -```python -def execute_with_fallback(g, operations): - try: - return g.chain(operations) - except GFQLSchemaError as e: - if e.code == ErrorCode.E301: - # Try without the problematic filter - field = e.context.get('field') - logger.warning(f"Removing filter on missing column: {field}") - # ... modify operations ... - return g.chain(modified_operations) - raise -``` - -## Backward Compatibility Notes - -1. **Empty chains remain valid** - No breaking change -2. **Old validation module still exists** - But deprecated -3. **Error handling is stricter** - Errors that were warnings may now raise - -## Benefits of Migration - -1. **Performance**: No separate validation pass needed -2. **Developer Experience**: Errors caught immediately during construction -3. **Better Messages**: Structured errors with suggestions -4. **Type Safety**: Specific exception types for different error categories -5. **Flexibility**: Choose between fail-fast and collect-all modes -

First phase (Steps 1.x) should be general analysis of the repo, feature: Do steps around reading our GFQL impl/examples and PyGraphistry regular APIs around GFQL Wire Protocol and Python API, and saving out some relevant knowledge to a lookup file with back references to our repo (file, lineno, snippet). Then enumerate our sketch.md features, and for each, create a sub analysis step (1.X.1, 1.X.2, 1.X.3) about that feature, how it relates, and some critical review of bugs/risks/improvements/etc. After, do a combined critical review, step 1.X+1. Finally, make a new sketch1X.md that supercedes our sketch.md, and is complete unto itself. Do a follow-on step to compare the two and fix sketch1X.md for whatever missed. Once all that is ready, make a new step steries, 2.*, whose first step is to review 1.* and come up with some key different User Personas and key different User Scenarios for each one around these features. Then another step to review those, and if any key gaps, add more Personas/Scenarios. Then, start step seris 3.*. First step is to add a subset for every user persona x user scenario for a role play. Each individual step is to generate a role_play_user_X_scenario_Y.md (catalog these), where you fill out the role play of that scenario getting solved via the wire protocol or python api. End each role play .md with a bit lof localized analysis of what worked, what didn't, and how to improve, with a prioritized breakdown of regular P0 (absolutely & urgenetly required) to P4/P5 (probably won't happen superficial nice-to-haves.) Finally, do a step series 4.X that reviews our 2.* and 3.* to create a sketch3X.md . Make a stp that is a metastep: read all our 2x/3x files & comments, and for each one, create a fresh step to update our 3X.md with appropriate fixes." +**Goal**: Develop comprehensive product specification for GFQL Programs through analysis, user research, and iterative refinement +**Description**: Multi-phase PRD development process starting with technical analysis, moving through user persona development and role-playing, ending with refined specification +**Context**: GFQL is PyGraphistry's declarative query language.

UMAPMixin, + FeatureMixin, ConditionalMixin, + LayoutsMixin, + ComputeMixin, PlotterBase # <-- GFQL exposed via ComputeMixin +): +``` + +#### 3. **ComputeMixin** (`/graphistry/compute/ComputeMixin.py`) + +Provides the actual implementation bridge (file:462-472): + +```python +def chain(self, *args, **kwargs): + return chain_base(self, *args, **kwargs)

Protocol Format + +#### 1. **Request Format** (`/graphistry/compute/chain_remote.py`) + +Remote execution sends requests to the server API (file:67-89): + +```python +# API endpoint +url = f"{self.base_url_server()}/api/v2/etl/datasets/{dataset_id}/gfql/{output_type}" + +# Request body structure +request_body = { + "gfql_operations": chain_json['chain'], # List of AST operations +

"Content-Type": "application/json", +} +``` + +#### 2. **Response Handling** (`/graphistry/compute/chain_remote.py`) + +The response format depends on `output_type` and `format` (file:93-166): + +- **Shape queries** (`output_type="shape"`): Returns metadata DataFrame +- **Graph queries** (`output_type="all"`): Returns nodes and edges + - JSON format: `{"nodes": [...], "edges": [...]}` + - CSV/Parquet: ZIP file containing separate nodes/edges files +- **Partial queries** (`output_type="nodes"` or `"edges"`): Single DataFrame + +#### 3. **Output Type Definitions** (`/graphistry/models/compute/chain_remote.py`) + +```python +# Graph-oriented outputs (file:5-6) +OutputTypeGraph = Literal["all", "nodes", "edges", "shape"] + +# DataFrame outputs (file:11-12)

self._dataset_id +``` + +### Error Handling Patterns + +#### 1. **Validation** (`/graphistry/compute/chain_remote.py`) + +- Input validation (file:42-48): Checks output_type, engine values +- Chain validation (file:64-65): Validates AST structure before sending +- Response validation (file:91): Uses `response.raise_for_status()` + +#### 2. **Error Types** + +Common error scenarios handled: +- Missing dataset_id (ValueError) +- Invalid output_type or format (ValueError) +- HTTP errors (requests.HTTPError) +- Deserialization errors based on data type detection + +### Python Remote Execution + +Related API for arbitrary Python execution (`/graphistry/compute/python_remote.py`): + +```python +# Execute Python code remotely (file:34-96) +def python_remote_generic( + self: Plottable, + code:

+### Integration Architecture + +The API follows a layered architecture: + +1. **User API Layer**: `Plotter` class with friendly methods +2. **Protocol Layer**: `Plottable` interface defining contracts +3. **Implementation Layer**: `ComputeMixin` bridging to compute modules +4. **Execution Layer**: `chain.py` (local) and `chain_remote.py` (remote) +5. **Transport Layer**: HTTP/JSON wire protocol to server + +This separation enables: +- Clean API surface for users +- Protocol-based testing and mocking +- Engine-agnostic implementation (pandas vs cudf) +- Seamless local/remote execution switching +- Session isolation for multi-tenant scenarios + +### Usage Patterns + +#### Basic Local Execution +```python +import graphistry +from graphistry import n, e_forward + +g = graphistry.edges(df, 'src', 'dst') +g2 = g.chain([n({"type": "person"}), e_forward(), n({"type": "company"})]) +``` + +#### Remote Execution with Auto-upload +```python +# Automatically uploads if

The feature enables multiple graph bindings, remote graph loading, and complex graph combinators while maintaining backward compatibility with existing Chain operations. + +## 1.3.1.1: Relationship to Current Chain Architecture + +### How QueryDAG Extends the Single-Chain Model + +The current GFQL architecture is built around a linear chain of operations: + +```python +# Current: Linear sequence +g.chain([ + n({"type": "person"}), + e_forward(), + n({"type": "company"}) +]) +``` + +QueryDAG extends this to support: + +1. **Multiple Named Graphs**: Instead of operating on a single implicit graph, QueryDAG introduces a binding environment where multiple graphs can be named and referenced: + +```python +# Proposed: DAG with multiple graphs +ChainGraph({ + "people": Chain([n({"type": "person"})]), + "companies": Chain([n({"type": "company"})]), + "connections": Chain(ref="people", chain=[e_forward()]) +}) +``` + +2. **Lexical Scoping**: References follow lexical scoping rules, where the closest binding to a reference is used. This is similar to variable scoping in programming languages. + +3. **Explicit Output Selection**: While chains implicitly return the final operation's result, QueryDAG allows explicit output selection via the `output` field. + +### Reusable Components from Current Architecture + +The following components can be directly reused: + +1. **AST Infrastructure**: + - `ASTSerializable` base class for JSON serialization + - `ASTObject` interface with `__call__` and `reverse` methods + - Existing AST nodes (`ASTNode`, `ASTEdge`) + - Predicate system remains unchanged + +2. **Execution Engine**: + - The 3-phase algorithm (forward/reverse/combine) can be applied to each sub-chain + - `combine_steps()` function for merging results + - Engine abstraction (pandas/cudf) works as-is + +3. **Remote Execution**: + - `chain_remote.py` infrastructure can be extended + - Wire protocol JSON structure naturally extends to nested operations + - Authentication and session handling remain the same + +4. **Plottable Integration**: + - Results still return Plottable objects + - Node/edge bindings work the same way + - Visualization settings preservation + +### New Components Required + +1. **QueryDAG AST Node**: +```python +class QueryDAG(ASTSerializable): + def __init__(self, graph: Dict[str, Union[Chain, 'QueryDAG']], output: Optional[str] = None): + self.graph = graph + self.output = output or list(graph.keys())[-1] + + def validate(self): + # Validate binding names match pattern ^[a-zA-Z_][a-zA-Z0-9_-]*$ + # Check for circular references + # Ensure output exists in graph +``` + +2. **Reference Resolution**: + -

Each binding holds a full Plottable (nodes + edges DataFrames) + - Need reference counting or garbage collection for intermediate results + - Consider lazy evaluation for unused bindings + +2. **Execution Optimization**: + - Parallel execution of independent subgraphs + - Common subexpression elimination + - Query planning for optimal execution order + +3. **Network Overhead**: + - Larger wire protocol messages + - Multiple remote graph fetches + -

Maximum number of concurrent bindings + - Total memory usage caps + - Timeout for long-running DAGs + +## 1.3.1.3: Critical Review + +### Potential Bugs/Edge Cases + +1. **Circular References**: +```python +# This should be detected and rejected +ChainGraph({ + "a": Chain(ref="b", chain=[...]), + "b": Chain(ref="a", chain=[...]) +}) +``` + +2. **Name Collisions**: +```python +# Shadowing in nested scopes +ChainGraph({ + "data": RemoteGraph("abc"), + "nested": ChainGraph({ + "data": RemoteGraph("xyz"), # Shadows outer "data" + "result": Chain(ref="data") # Which one? + }) +}) +``` + +3. **Missing References**: +```python +# Reference to non-existent binding +Chain(ref="nonexistent", chain=[...]) +``` + +4. **Resource Exhaustion**: + - Loading too many large remote graphs + - Deep nesting causing stack overflow + - Combinatorial explosion in graph combinations + +### Security Risks + +1. **Resource Exhaustion Attacks**: + - Malicious DAGs with excessive bindings + - Recursive structures consuming memory + - Remote graph fetching as DoS vector + +2. **Access Control**: + - Ensure remote graph access respects permissions + - Prevent information leakage through error messages + - Validate dataset_id format to prevent injection + +3. **Execution Limits**: +```python +class DAGExecutionLimits: + max_bindings = 100 + max_nesting_depth = 10 + max_execution_time = 300 # seconds + max_memory_usage = 1024 # MB + max_remote_fetches = 20 +``` + +### Suggested Improvements + +1. **Lazy Evaluation**: + -

First phase (Steps 1.x) should be general analysis of the repo, feature: Do steps around reading our GFQL impl/examples and PyGraphistry regular APIs around GFQL Wire Protocol and Python API, and saving out some relevant knowledge to a lookup file with back references to our repo (file, lineno, snippet). Then enumerate our sketch.md features, and for each, create a sub analysis step (1.X.1, 1.X.2, 1.X.3) about that feature, how it relates, and some critical review of bugs/risks/improvements/etc. After, do a combined critical review, step 1.X+1. Finally, make a new sketch1X.md that supercedes our sketch.md, and is complete unto itself. Do a follow-on step to compare the two and fix sketch1X.md for whatever missed. Once all that is ready, make a new step steries, 2.*, whose first step is to review 1.* and come up with some key different User Personas and key different User Scenarios for each one around these features. Then another step to review those, and if any key gaps, add more Personas/Scenarios. Then, start step seris 3.*. First step is to add a subset for every user persona x user scenario for a role play. Each individual step is to generate a role_play_user_X_scenario_Y.md (catalog these), where you fill out the role play of that scenario getting solved via the wire protocol or python api. End each role play .md with a bit lof localized analysis of what worked, what didn't, and how to improve, with a prioritized breakdown of regular P0 (absolutely & urgenetly required) to P4/P5 (probably won't happen superficial nice-to-haves.) Finally, do a step series 4.X that reviews our 2.* and 3.* to create a sketch3X.md . Make a stp that is a metastep: read all our 2x/3x files & comments, and for each one, create a fresh step to update our 3X.md with appropriate fixes." -**Goal**: Develop comprehensive product specification for GFQL Programs through analysis, user research, and iterative refinement -**Description**: Multi-phase PRD development process starting with technical analysis, moving through user persona development and role-playing, ending with refined specification -**Context**: GFQL is PyGraphistry's declarative query language.

This is similar to variable scoping in programming languages. - -3. **Explicit Output Selection**: While chains implicitly return the final operation's result, QueryDAG allows explicit output selection via the `output` field. - -### Reusable Components from Current Architecture - -The following components can be directly reused: - -1. **AST Infrastructure**: - - `ASTSerializable` base class for JSON serialization - - `ASTObject` interface with `__call__` and `reverse` methods - - Existing AST nodes (`ASTNode`, `ASTEdge`) - - Predicate system remains unchanged - -2. **Execution Engine**: - - The 3-phase algorithm (forward/reverse/combine) can be applied to each sub-chain - - `combine_steps()` function for merging results - - Engine abstraction (pandas/cudf) works as-is - -3. **Remote Execution**: - - `chain_remote.py` infrastructure can be extended - - Wire protocol JSON structure naturally extends to nested operations - - Authentication and session handling remain the same - -4. **Plottable Integration**: - - Results still return Plottable objects - - Node/edge bindings work the same way - - Visualization settings preservation -

-### Performance Implications - -1. **Memory Management**: - - Each binding holds a full Plottable (nodes + edges DataFrames) - - Need reference counting or garbage collection for intermediate results - - Consider lazy evaluation for unused bindings - -2. **Execution Optimization**: - - Parallel execution of independent subgraphs - - Common subexpression elimination - - Query planning for optimal execution order -

Direction-specific logic - -### 6. `/graphistry/compute/ASTSerializable.py` - Serialization Base - -**Purpose**: Base class for JSON serialization of AST components - -**Key Methods**: -- `to_json()` (file:19-30) - Generic serialization - - Adds 'type' field with class name - - Serializes all non-reserved attributes - -- `from_json()` (file:33-40) - Generic deserialization - - Uses 'type' field to determine class - - Passes remaining fields to constructor - -## Design Patterns - -### 1. **Visitor Pattern** -AST nodes implement `__call__()` to process graph data, with the chain orchestrating traversal. - -### 2. **Builder Pattern** -Operations compose into chains, building complex queries from simple primitives. - -### 3. **Strategy Pattern** -Predicates encapsulate filtering strategies that can be swapped at runtime. - -### 4. **Memento Pattern** -JSON serialization enables saving/restoring query state. - -## Integration Points - -### 1. **Engine Abstraction** -- Supports pandas (CPU) and cudf (GPU) DataFrames -- Engine selection via `resolve_engine()` helper -- Automatic engine detection based on data type - -### 2. **Plottable Integration** -- All operations work on Plottable objects -- Maintains node/edge bindings throughout -- Preserves visualization settings - -### 3. **Remote Execution** -- Seamless switch between local and remote -- Same API for both modes -- Automatic data upload when needed - -## Example Usage Patterns - -### Basic Node Filtering -```python -from graphistry import n, e_forward - -# Find all person nodes -g.chain([n({"type": "person"})]) -``` - -### Multi-hop Traversal -```python -# Find transactions between risky entities -g.chain([ - n({"risk": gt(0.8)}), - e_forward({"type": "transfer"}, hops=2), - n({"risk": gt(0.8)}) -]) -``` - -### Named Operations -```python -# Label intermediate results -g.chain([ - n({"type": "account"}, name="source_accounts"), - e_forward(name="transfers"), - n({"type": "account"}, name="dest_accounts") -]) -# Access via g._nodes.source_accounts, g._edges.transfers -``` - -### Complex Predicates -```python -# Combine multiple predicate types -g.chain([ - n({ - "created_date": is_month_start(), - "name": contains("Corp"), - "value": between(1000, 10000) - }) -]) -``` - -## Wire Protocol Examples - -### Local Chain Execution -```python -chain = Chain([ - {"type": "Node", "filter_dict": {"type": "person"}}, - {"type": "Edge", "direction": "forward", "hops": 2}, - {"type": "Node", "filter_dict": {"type": "company"}} -]) -g2 = g.chain(chain) -``` - -### Remote Execution Request -```json -{ - "gfql_operations": [ - { - "type": "Node", - "filter_dict": {"risk": {"type": "GT", "val": 0.5}} - }, - { - "type": "Edge", - "direction": "forward", - "edge_match": {"amount": {"type": "Between", "lower": 1000, "upper": 5000}} - } - ], - "format": "parquet", - "engine": "cudf" -} -``` - -## Performance Considerations - -1. **Wavefront Optimization**: The algorithm maintains a wavefront of active nodes rather than revisiting the entire graph - -2. **Dead-end Pruning**: The reverse pass ensures only nodes on complete paths are returned - -3. **GPU Acceleration**: When using cudf engine, operations leverage GPU parallelism - -4. **Remote Execution**: For large graphs, server-side execution avoids data transfer overhead - -5. **Column Subsetting**: Remote queries can request only needed columns to reduce bandwidth - -## Extension Points for DAG Support - -The current architecture could be extended for DAG program support by: - -1. **Program AST Node**: New AST type that contains a sequence of operations -2. **Variable Binding**: Allow naming intermediate results for reuse -3. **Conditional Logic**: Add branching based on graph properties -4. **Aggregation Operators**: Support for counting, grouping operations -5. **Subprogram Composition**: Enable nesting of program definitions - -The existing serialization framework and remote execution infrastructure provide a solid foundation for these extensions. - -## PyGraphistry API Integration - -### Entry Points - -GFQL functionality is exposed through the PyGraphistry API via several key integration points: - -#### 1. **Plottable Interface** (`/graphistry/Plottable.py`) - -The `Plottable` protocol (file:48-791) defines the main API contracts: - -```python -# Local chain execution (file:419-423) -def chain(self, ops: Union[Any, List[Any]]) -> 'Plottable': - """ops is Union[List[ASTObject], Chain]""" - ... - -# Remote chain execution (file:425-440) -def chain_remote( - self: 'Plottable', - chain: Union[Any, Dict[str, JSONVal]], - api_token: Optional[str] = None, - dataset_id: Optional[str] = None, - output_type: OutputTypeGraph = "all", - format: Optional[FormatType] = None, - df_export_args: Optional[Dict[str, Any]] = None, - node_col_subset: Optional[List[str]] = None, - edge_col_subset: Optional[List[str]] = None, - engine: Optional[Literal["pandas", "cudf"]] = None -) -> 'Plottable': - ... - -# Remote shape query (file:442-456) -def chain_remote_shape( - self: 'Plottable', - chain: Union[Any, Dict[str, JSONVal]], - # ... same parameters as chain_remote -) -> pd.DataFrame: - ... -``` - -#### 2. **Plotter Class Hierarchy** (`/graphistry/plotter.py`) - -The main `Plotter` class (file:21-93) inherits from multiple mixins: - -```python -class Plotter( - KustoMixin, SpannerMixin, - CosmosMixin, NeptuneMixin, - HeterographEmbedModuleMixin, - SearchToGraphMixin, - DGLGraphMixin, ClusterMixin, - UMAPMixin, - FeatureMixin, ConditionalMixin, - LayoutsMixin, - ComputeMixin, PlotterBase # <-- GFQL exposed via ComputeMixin -): -``` - -#### 3. **ComputeMixin** (`/graphistry/compute/ComputeMixin.py`) - -Provides the actual implementation bridge (file:462-472): - -```python -def chain(self, *args, **kwargs): - return chain_base(self, *args, **kwargs) -chain.__doc__ = chain_base.__doc__ - -def chain_remote(self, *args, **kwargs) -> Plottable: - return chain_remote_base(self, *args, **kwargs) -chain_remote.__doc__ = chain_remote_base.__doc__ - -def chain_remote_shape(self, *args, **kwargs) -> pd.DataFrame: - return chain_remote_shape_base(self, *args, **kwargs) -chain_remote_shape.__doc__ = chain_remote_shape_base.__doc__ -``` - -### Wire Protocol Format - -#### 1. **Request Format** (`/graphistry/compute/chain_remote.py`) - -Remote execution sends requests to the server API (file:67-89): - -```python -# API endpoint -url = f"{self.base_url_server()}/api/v2/etl/datasets/{dataset_id}/gfql/{output_type}" - -# Request body structure -request_body = { - "gfql_operations": chain_json['chain'], # List of AST operations - "format": format, # "json", "csv", "parquet" - "node_col_subset": node_col_subset, # Optional: limit returned columns - "edge_col_subset": edge_col_subset, # Optional: limit returned columns - "df_export_args": df_export_args, # Optional: pandas export args - "engine": engine # Optional: "pandas" or "cudf" -} - -# Headers -headers = { - "Authorization": f"Bearer {api_token}", - "Content-Type": "application/json", -} -``` - -#### 2. **Response Handling** (`/graphistry/compute/chain_remote.py`) - -The response format depends on `output_type` and `format` (file:93-166): - -- **Shape queries** (`output_type="shape"`): Returns metadata DataFrame -- **Graph queries** (`output_type="all"`): Returns nodes and edges - - JSON format: `{"nodes": [...], "edges": [...]}` - - CSV/Parquet: ZIP file containing separate nodes/edges files -- **Partial queries** (`output_type="nodes"` or `"edges"`): Single DataFrame - -#### 3. **Output Type Definitions** (`/graphistry/models/compute/chain_remote.py`) - -```python -# Graph-oriented outputs (file:5-6) -OutputTypeGraph = Literal["all", "nodes", "edges", "shape"] - -# DataFrame outputs (file:11-12) -OutputTypeDf = Literal["table", "shape"] - -# JSON outputs (file:14-15) -OutputTypeJson = Literal["json"] - -# Format types (file:8-9) -FormatType = Literal["json", "csv", "parquet"] -``` - -### Authentication and Session Handling - -#### 1. **Session Management** (`/graphistry/client_session.py`) - -Each Plotter instance maintains session state (file:26-100): - -```python -class ClientSession: - """Holds all configuration and authentication state""" - - # Authentication state - api_key: Optional[str] - api_token: Optional[str] # JWT token - - # Server configuration - hostname: str - protocol: str - api_version: ApiVersion # 1 or 3 - - # Organization settings - org_name: Optional[str] - privacy: Optional[Privacy] -``` - -#### 2. **Token Refresh** (`/graphistry/compute/chain_remote.py`) - -Automatic token refresh on remote calls (file:30-33): - -```python -if not api_token: - from graphistry.pygraphistry import PyGraphistry - PyGraphistry.refresh() # Refreshes JWT if needed - api_token = PyGraphistry.api_token() -``` - -#### 3. **Dataset Upload** (`/graphistry/compute/chain_remote.py`) - -Automatic upload if no dataset_id exists (file:35-40): - -```python -if not dataset_id: - dataset_id = self._dataset_id - -if not dataset_id: - self = self.upload(validate=validate) # Uploads current graph - dataset_id = self._dataset_id -``` - -### Error Handling Patterns - -#### 1. **Validation** (`/graphistry/compute/chain_remote.py`) - -- Input validation (file:42-48): Checks output_type, engine values -- Chain validation (file:64-65): Validates AST structure before sending -- Response validation (file:91): Uses `response.raise_for_status()` - -#### 2. **Error Types** - -Common error scenarios handled: -- Missing dataset_id (ValueError) -- Invalid output_type or format (ValueError) -- HTTP errors (requests.HTTPError) -- Deserialization errors based on data type detection - -### Python Remote Execution - -Related API for arbitrary Python execution (`/graphistry/compute/python_remote.py`): - -```python -# Execute Python code remotely (file:34-96) -def python_remote_generic( - self: Plottable, - code: Union[str, Callable[..., object]], - api_token: Optional[str] = None, - dataset_id: Optional[str] = None, - format: Optional[FormatType] = 'json', - output_type: Optional[OutputTypeAll] = 'json', - engine: Literal["pandas", "cudf"] = "cudf", - run_label: Optional[str] = None, - validate: bool = True -) -> Union[Plottable, pd.DataFrame, Any]: - ... - -# Request format (file:133-139) -request_body = { - "execute": code_indented, # Python code with task(g) function - "engine": engine, - "run_label": run_label, # Optional job tracking - "format": format, - "output_type": output_type -} -``` - -### Integration Architecture - -The API follows a layered architecture: - -1. **User API Layer**: `Plotter` class with friendly methods -2. **Protocol Layer**: `Plottable` interface defining contracts -3. **Implementation Layer**: `ComputeMixin` bridging to compute modules -4. **Execution Layer**: `chain.py` (local) and `chain_remote.py` (remote) -5. **Transport Layer**: HTTP/JSON wire protocol to server - -This separation enables: -- Clean API surface for users -- Protocol-based testing and mocking -- Engine-agnostic implementation (pandas vs cudf) -- Seamless local/remote execution switching -- Session isolation for multi-tenant scenarios - -### Usage Patterns - -#### Basic Local Execution -```python -import graphistry -from graphistry import n, e_forward - -g = graphistry.edges(df, 'src', 'dst') -g2 = g.chain([n({"type": "person"}), e_forward(), n({"type": "company"})]) -``` - -#### Remote Execution with Auto-upload -```python -# Automatically uploads if needed -g2 = g.chain_remote([n({"type": "person"}), e_forward(), n({"type": "company"})]) -``` - -#### Optimized Remote Query -```python -# Get just shape info without full data transfer -shape_df = g.chain_remote_shape( - [n({"risk": gt(0.8)}), e_forward(hops=2)], - engine='cudf', # Force GPU - node_col_subset=['id', 'risk'] # Limit columns -) -if len(shape_df) > 0: - # Fetch full results only if matches exist - g2 = g.chain_remote([...]) -``` \ No newline at end of file diff --git a/AI_PROGRESS/gfql-programs-spec/persona_scenario_gap_analysis.md b/AI_PROGRESS/gfql-programs-spec/persona_scenario_gap_analysis.md deleted file mode 100644 index 7ff307e0d3..0000000000 --- a/AI_PROGRESS/gfql-programs-spec/persona_scenario_gap_analysis.md +++ /dev/null @@ -1,72 +0,0 @@ -# Persona/Scenario Gap Analysis -

resolve circular import between chain.py and validate_schema.py - Move validate_schema method to Chain class to avoid circular import - Fix Chain validation to properly raise GFQLTypeError/GFQLSyntaxError - Update _validate_fields to raise proper exceptions instead of asserts - Override validate() to collect all errors when collect_all=True - Update from_json to raise GFQLSyntaxError instead of asserts - Pass validate parameter through to ASTObject_from_json All tests now pass with proper error handling and no circular imports. --- graphistry/compute/chain.py | 106
