ArvinDevel opened a new pull request #927: BP-24: BookieScanner: Enhance Data Integrity URL: https://github.com/apache/bookkeeper/pull/927 Descriptions of the changes in this PR: Currently Bookie can't deal entry losing gracefully, the AutoRecovery is restricted to the bookie level, which means the AutoRecovery takes effect only after bookie is down. However when a disk fails, either or both the ledger index files and entry log files could potentially become corrupt. BookKeeper needs to provide mechanisms to identify and handle these problems. In this BP, we introduce Bookie Scanner, which is a background task, to scan index files and entry log files to detect possible corruptions. Since data corruption may happen at any time on any block on any Bookie, it is important to identify these errors in a timely manner. This way, the bookie can remove/compact corrupted entries and re-replicate entries from other replicas, to maintain data integrity and reduce client errors.
