    + *
  1. Container State Summary — per lifecycle-state counts (OPEN, CLOSING, + * QUASI_CLOSED, CLOSED) are identical between SCM and Recon after a full sync.
    2. + *
  2. Container Health Summary — UNHEALTHY_CONTAINERS derby table counts in + * Recon match exactly the health states classified by SCM's ReplicationManager + * after both process the same container replica state.
    3. + *
+ * + *

Health states covered: + *

    + *
  • {@code UNDER_REPLICATED} — RF3 CLOSED container with 1 replica removed from + * both SCM and Recon → 2 of 3 replicas present.
    • + *
  • {@code OVER_REPLICATED} — RF1 CLOSED container with a phantom replica injected + * into both SCM and Recon → 2 replicas for an RF1 container.
    • + *
  • {@code MISSING} — RF1 CLOSED container with all replicas removed from both, + * {@code numberOfKeys=1} → SCM RM: {@code MISSING} (via + * {@code RatisReplicationCheckHandler}), Recon: {@code MISSING}.
    • + *
  • {@code EMPTY_MISSING} — RF1 CLOSING container with all replicas removed + * from both, {@code numberOfKeys=0} (default). SCM RM emits both: + * {@code getStat(MISSING)} (via {@code ClosingContainerHandler}) for these containers + * AND {@code getStat(EMPTY)} (via {@code EmptyContainerHandler} case 3) for the + * CLOSED contrast group below. When the same container is both MISSING + * (no replicas → health=MISSING in SCM) and EMPTY (no keys → numberOfKeys=0), + * Recon stores it as {@code EMPTY_MISSING}.
    • + *
  • {@code EMPTY} (contrast to {@code EMPTY_MISSING}) — RF1 CLOSED container + * with 0 replicas and {@code numberOfKeys=0}, never created on any datanode. + * SCM RM: {@code EMPTY} (via {@code EmptyContainerHandler} case 3, which fires + * before {@code RatisReplicationCheckHandler} and stops the chain). + * Recon: also {@code EMPTY} — NOT stored in {@code UNHEALTHY_CONTAINERS}. This + * shows that the same content properties (0 keys + 0 replicas) produce a different + * classification depending on lifecycle state: CLOSING → MISSING/EMPTY_MISSING, + * CLOSED → EMPTY/not-stored.
    • + *
  • {@code MIS_REPLICATED} — NOT COVERED: requires a rack-aware placement policy + * configured with a specific multi-rack DN topology, not available in mini-cluster + * integration tests. Expected count = 0 in both SCM and Recon.
    • + *
+ * + *

Key design notes on EMPTY, MISSING, and EMPTY_MISSING: + *

    + *
  • A container is stored as {@code EMPTY_MISSING} in Recon when it is + * classified as {@code MISSING} by SCM's RM (no replicas → health=MISSING) + * AND the container is empty (no OM-tracked keys → numberOfKeys=0). + * SCM's RM emits {@code getStat(MISSING)} for such containers, while Recon + * refines this to {@code EMPTY_MISSING} in {@code handleMissingContainer()}. + *
    • + *
  • MISSING path: CLOSED + 0 replicas + {@code numberOfKeys > 0} → + * {@code EmptyContainerHandler} case 3 does NOT fire (numberOfKeys≠0) → + * {@code RatisReplicationCheckHandler} fires → SCM: {@code MISSING}, + * Recon: {@code MISSING}.
    • + *
  • EMPTY_MISSING path: CLOSING + 0 replicas + {@code numberOfKeys == 0} → + * {@code ClosingContainerHandler} fires → SCM: {@code MISSING} (getStat(MISSING)++), + * Recon: {@code EMPTY_MISSING}. The container is simultaneously MISSING (no replicas, + * health=MISSING) and EMPTY (no keys, numberOfKeys=0).
    • + *
  • EMPTY (not EMPTY_MISSING) path: CLOSED + 0 replicas + + * {@code numberOfKeys == 0} → {@code EmptyContainerHandler} case 3 fires + * first (CLOSED state, before {@code RatisReplicationCheckHandler}) → + * SCM: {@code EMPTY} (getStat(EMPTY)++). Even though this container also has 0 + * replicas, the chain stops at EMPTY and never reaches MISSING classification. + * Recon also classifies it as EMPTY and does NOT store it in + * {@code UNHEALTHY_CONTAINERS}. This is the critical boundary.

deletion candidates — route those to `/keys/deletePending`. +- When combining filters, include every filter the user mentioned (`replicationType`, `keySize`, `creationDate`). +- If the response includes `lastKey` and the user wants more results, suggest pagination with `prevKey`. +- If `status` is `INITIALIZING`, tell the user Recon is still syncing OM metadata and to retry shortly. + +--- + +## **Schema: FileSizeUtilization** + +**Purpose:** + +Represents the **distribution of files across volumes and buckets by size category and count**. + +Returned by the `/utilization/filesize` endpoint in Recon to show how many files exist of specific sizes within each bucket. + +Used for analyzing **storage utilization trends**, **file size skew**, and **capacity consumption patterns**. + +--- + +### **Fields** + +Each entry in the array describes a unique combination of volume, bucket, and file-size grouping. + +- **volume** *(string)* — Name of the Ozone **volume** containing the files. + + Identifies the logical namespace root under which the bucket resides. + + *Example:* `"vol-2-04168"` + +- **bucket** *(string)* — Name of the **bucket** under the specified volume. + + Represents the immediate container grouping for files (keys) of this size class. + + *Example:* `"bucket-0-11685"` + +- **fileSize** *(number)* — Size (in bytes) of the file or file group represented by this record. + + Each record aggregates all files of the same size under a given volume/bucket pair. + + *Example:* `1024` + +- **count** *(integer)* — Number of files (keys) found with the exact or approximate file size defined in `fileSize`. + + Indicates how many files contribute to that utilization point. + + *Example:* `1` + + +--- + +### **Example** + +```json +[ + { "volume": "vol-2-04168", "bucket": "bucket-0-11685", "fileSize": 1024, "count": 1 }, + { "volume": "vol-2-04168", "bucket": "bucket-1-41795", "fileSize": 1024, "count": 1 }, + { "volume": "vol-2-04168", "bucket": "bucket-2-93377", "fileSize": 1024, "count": 1 }, + { "volume": "vol-2-04168", "bucket": "bucket-3-50336", "fileSize": 1024, "count": 2 } +] + +``` + +--- + +### **Usage Notes** + +- Used in Recon to **quantify data distribution** by file size across volumes and buckets. +- Each record represents aggregated counts of files with identical or rounded sizes. +- Helps identify **hot buckets** (those with many small files) or **storage inefficiency** (many tiny keys inflating metadata). +- Supports **capacity planning** by correlating `fileSize × count` for total storage consumption per bucket. +- May be combined with `MetadataDiskUsage` or `MetadataSpaceDist` for richer cluster utilization analytics. + +--- + +### **Interpretation Example** + +If the dataset shows many entries with `fileSize = 1024` and high `count` values across multiple buckets, + +it implies heavy use of small files — common in workloads with metadata-intensive operations or frequent small writes. + +--- + +### **Natural-Language Query Mappings** + +| Example Query | Maps To | +| --- | --- | +| “Show how many files exist per bucket by size.” | `volume`, `bucket`, `fileSize`, `count` | +| “Which buckets have the most small files?” | Filter where `fileSize` < threshold, sort by `count` | +| “What is the total number of 1 KB files?” | Aggregate all entries where `fileSize = 1024`, sum `count` | +| “List buckets under vol-2-04168 with large files.” | Filter by `volume`, sort by descending `fileSize` | +| “How is file size distributed across volumes?” | Group by `volume`, aggregate `fileSize × count` | + +--- + +### **Routing Guide** + +- Use this schema for **data size analytics**, **file count summaries**, and **storage optimization queries**. +- When the query includes phrases like *“file size utilization,” “file count by bucket,” “how many small files,”* or *“storage distribution,”* this schema applies. +- For broader space usage (including replicas), correlate with `MetadataDiskUsage`. +- If user asks for totals or averages, aggregate across `count` and `fileSize` fields. +- If `fileSize` appears constant across many buckets, highlight uneven data spread as a cluster optimization insight. + +--- + +## **Schema: ContainerUtilization** + +**Purpose:** + +Represents the **distribution of container sizes and counts** across the Ozone cluster. + +Returned by the `/utilization/containers` endpoint in Recon. + +Used to analyze **how many containers exist at specific size levels**, identify imbalance, and assist in capacity planning. + +--- + +### **Fields** + +Each record in the array corresponds to one container size category and the number of containers that fall into it. + +- **containerSize** *(number)* — The size (in bytes) of containers within this utilization group. + + Reflects total data stored in each container class. + + Often reported as powers of two (e.g., 1 GB, 2 GB). + + *Example:* `2147483648` + +- **count** *(number)* — Number of containers that have the specified `containerSize`. + + Indicates the frequency or volume distribution of containers by size. + + *Example:* `9` + + +--- + +### **Example** + +```json +[ + { "containerSize": 2147483648, "count": 9 }, + { "containerSize": 1073741824, "count": 3 } +] + +``` + +--- + +### **Usage Notes** + +- Used to **analyze space allocation patterns** among Ozone containers. +- Helps detect uneven data distribution across pipelines or DataNodes. +- A large number of smaller containers can imply fragmented writes or high namespace churn. +- Larger container groups indicate bulk or aggregated data usage patterns. +- Useful for **capacity diagnostics**, **container balancing**, and **replication efficiency monitoring** in Recon dashboards. + +--- + +### **Interpretation Example** + +If `containerSize = 2 GB` has a higher count than `1 GB`, the cluster stores most data in full-sized containers. + +If smaller containers dominate, it may indicate premature container closures or frequent small writes. + +--- + +### **Natural-Language Query Mappings** + +| Example Query | Maps To | +| --- | --- | +| “How many containers are 2 GB in size?” | Filter where `containerSize = 2147483648`, read `count` | +| “List all container sizes and their counts.” | Iterate through `containerSize` and `count` | +| “What is the most common container size in the cluster?” | Highest `count` value | +| “Show container size distribution.” | Aggregate full array of `containerSize` vs `count` | +| “Are most containers small or large?” | Compare counts between lower and higher size ranges | + +--- + +### **Routing Guide** + +- Use `ContainerUtilization` when queries mention *“container size,” “container distribution,” “storage utilization per container,”* or *“how many containers of size X.”* +- When user queries require percentage or trend analysis, compute relative proportions of `count` for each `containerSize`. +- For total capacity estimation, multiply `containerSize × count` and sum across entries. +- Integrate with `FileSizeUtilization` for combined container-to-file size analytics. +- If no containers are listed, infer that Recon’s container scan hasn’t completed or that all containers are currently empty. + +--- + diff --git a/hadoop-ozone/recon/src/main/resources/chatbot/recon-api.yaml
