> Currently the {{HoodieSourceOffset(implement in }} HUDI-1109 just keep the {{commitTime}} . In every min batch we consume the incremental data between {{(lastCommitTime, currentCommitTime]}} If it failed during the consuming, It will recovered from the offset state and continue to consuming the data between {{(lastCommitTime, currentCommitTime]}}. It is a commit level recovery.
> Introducing {{_hoodie_commit_seq_no}} to the {{offset}} may makes recovery more fine-grained to the record level just like the kafka. It will provide better real-time consumption.
