Phase 12: ROOT CAUSE FOUND - Duplicates due to Topic Persistence Bug Duplicate Analysis: - 8104 duplicates (66.5%), ALL read exactly 2 times - Suggests single rebalance/restart event - Duplicates start at offset 0, go to ~800 (50% of data) Investigation Results: 1. Offset commits ARE working (logging shows commits every 20 msgs) 2. NO rebalance during normal operation (only 10 OFFSET_FETCH at start) 3. Consumer error logs show REPEATED failures: 'Request was for a topic or partition that does not exist' 4. Broker logs show: 'no entry is found in filer store' for topic-2 Root Cause: Auto-created topics are NOT being reliably persisted to filer! - Producer auto-creates topic-2 - Topic config NOT saved to filer - Consumer tries to fetch metadata → broker says 'doesn't exist' - Consumer group errors → Sarama triggers rebalance - During rebalance, OffsetFetch returns -1 (no offset found) - Consumer starts from offset 0 again → DUPLICATES! The Flow: 1. Consumers start, read 0-800, commit offsets 2. Consumer tries to fetch metadata for topic-2 3. Broker can't find topic config in filer 4. Consumer group crashes/rebalances 5. OffsetFetch during rebalance returns -1 6. Consumers restart from offset 0 → re-read 0-800 7. Then continue from 800-1600 → 66% duplicates Next Fix: Ensure topic auto-creation RELIABLY persists config to filer before returning success to producers. |
