Bruce Wong updated FLINK-25330:
-------------------------------
Description:
h2. Background
When we use CDC to synchronize mysql data to HBase, we find that HBase deletes
only the last version of the specified rowkey when deleting mysql data. The
data of the old version still exists. You end up using the wrong data. And I
think its a bug of HBase connector.
The following figure shows Hbase data changes before and after mysql data is
deleted.
