             Summary: POC: Implement Dual Offset Tracking for WAL Replication
                 Key: HBASE-29064
                 URL: https://issues.apache.org/jira/browse/HBASE-29064
             Project: HBase
          Issue Type: Task
            Reporter: Vinayak Hegde


The current replication framework updates the WAL offset immediately after 
processing entries, which may lead to data loss in case of partial writes or 
failures before persisting the data to the backup storage (e.g., S3).
To address this:
 # {*}Delivered Offset{*}: Tracks entries sent to the replication endpoint.
 # {*}Committed Offset{*}: Tracks entries fully persisted to the backup storage.
