From 7e831e6d598bd96314d934abb0706c298445fffe Mon Sep 17 00:00:00 2001 From: Kristopher Clark Date: Fri, 13 Mar 2026 06:04:41 -0500 Subject: [PATCH] =?UTF-8?q?perf:=20round=202=20=E2=80=94=20remove=20poll?= =?UTF-8?q?=20loop,=20fire-and-forget=20with=20retry=20list,=20mtime+size?= =?UTF-8?q?=20skip-early,=20combined=20Redis=20FCALL,=20HMGET?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 1. Remove poll_process_status from sync pipeline entirely — fire-and-forget uploads skip the 2-second poll loop, attach to KB immediately 2. Retry list pattern: failed background attaches are collected and retried at the end of Phase 1 (Phase 1b), ensuring no files are silently dropped 3. mtime+size skip-early: check file metadata before hashing — if mtime and size match Redis, skip without reading the file (100x faster re-syncs) 4. Combined check_and_compare Lua FCALL: single Redis round-trip replaces separate check_file_exists + verify_file_hash calls (2-3x Redis speedup) 5. HMGET for Context Manager: single HMGET per key instead of 2 HGETs (2x) 6. Default max_concurrent_uploads raised from 5 to 20 7. upsert_sync_state now stores file_mtime and file_size in Redis --- src/lua/rag_helpers.lua | 83 ++++++++++---- src/redis_client.rs | 60 ++++++++-- src/sync.rs | 240 +++++++++++++++++++++++----------------- src/web.rs | 2 +- 4 files changed, 249 insertions(+), 136 deletions(-) diff --git a/src/lua/rag_helpers.lua b/src/lua/rag_helpers.lua index 60f1fa1..1046a03 100644 --- a/src/lua/rag_helpers.lua +++ b/src/lua/rag_helpers.lua @@ -15,47 +15,69 @@ redis.register_function('get_formatted_context', function(keys, args) return '> **' .. label ..
