Phase 6: Disk Read Fix Attempt #1 Added cache invalidation when extraction fails due to offset beyond cached chunk: - extractMessagesFromCache: Returns error when offset beyond cache - readHistoricalDataFromDisk: Invalidates bad cache and retries - invalidateCachedDiskChunk: New function to remove stale cache Problem Discovered: Cache invalidation works, but re-reading returns SAME incomplete data! Example: - Request offset 1764 - Disk read returns 764 messages (1000-1763) - Cache stores 1000-1763 - Request 1764 again → cache invalid → re-read → SAME 764 messages! Root Cause: ReadFromDiskFn (GenLogOnDiskReadFunc) is NOT returning incomplete data The disk files ACTUALLY only contain up to offset 1763 Messages 1764+ are either: 1. Still in memory (not yet flushed) 2. In a different file not being read 3. Lost during flush Test Results: 73.3% delivery (worse than before 87.9%) Cache thrashing causing performance degradation Next: Fix the actual disk read to handle gaps between flushed data and in-memory data |
