------------------------------------
Summary: Replication Observability Framework
Key: HBASE-26913
URL: https://issues.apache.org/jira/browse/HBASE-26913
Project: HBase
Issue Type: New Feature
Components: regionserver, Replication
Reporter: Rushabh Shah
Assignee: Rushabh Shah
{*}{*}In our production clusters, we have seen cases where data is present in
source cluster but not in the sink cluster and 1 case where data is present in
sink cluster but not in source cluster.
We have internal tools where we take incremental backup every day on both
source and sink clusters and we compare the hash of the data in both the
backups. We have seen many cases where hash doesn't match which means data is
not consistent between source and sink for that given day. The Mean Time To
Detect (MTTD) these inconsistencies is atleast 2 days and requires lot of
manual debugging.
We need some tool where we can reduce MTTD and requires less manual debugging.
I have attached design doc. Huge thanks to [~bharathv] to come up with this
design at my work place.
