Current implementation: `ManagedCursor` will skip the invalid data during `recover`, even if the feature `autoSkipNonRecoverableData ` is disabled. Ledger data invalid occurs in two cases: - ledger could not be found - some entries could not be found ---- #### Ledger could not be found When the ledger could not be found, we can recover data from ZK. But when switching ledger, data stored in ZK does not contain `individualDeletedMessages`, so we can only recover `markDeletedPosition` from ZK. The current code already implements this. ---- #### (<strong>High light</strong>) Some entries could not be found When the last entry is could not be found, we can trace the entry forward until one available entry is found, so as to recover data as much as possible. PR #17264 resolves this. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
