Priority: Major (was: Blocker)
> CDC From Mysql To Hbase Bugs
> ----------------------------
>
> Key: FLINK-28910
> URL: https://issues.apache.org/jira/browse/FLINK-28910
> Project: Flink
> Issue Type: Bug
> Components: Connectors / HBase
> Reporter: TE
> Priority: Major
> Labels: pull-request-available, stale-blocker
>
> I use Flink for CDC from Mysql to Hbase.
> The problem I encountered is that the Mysql record is updated (not deleted),
> but the record in hbase is deleted sometimes.
> I tried to analyze the problem and found the reason as follows:
> The update action of Mysql will be decomposed into delete + insert by Flink.
> The Hbase connector uses a mutator to handle this set of actions.
> However, if the order of these actions is not actively set, the processing of
> the mutator will not guarantee the order of execution.
> Therefore, when the update of Mysql is triggered, it is possible that hbase
> actually performed the actions in the order of put + delete, resulting in the
> data being deleted.
