Solution
Fix lost offset commits during consumer group rebalance by implementing synchronous commit flushing before partition revocation. Added RebalanceListener interface to ConsumerGroup that triggers FlushPendingCommitsBeforeRebalance() before partitions are revoked, with retry logic for RebalanceInProgress and IllegalGeneration errors. Maintains thread-safety with proper mutex coordination and ensures at-least-once delivery semantics without introducing message loss.
