-------------------------------------
Hi, Maybe we could support customized DeserializationSchema, and provide some
common implementation like DELETE_ALL, DELETE_LATEST, PADDING_EMPTY, to support
different scenarios.

> 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.
