-------------------------------

             Summary: Improve default flush strategy for HBase sink to make it work out-of-box
                 Key: FLINK-16496
                 URL: https://issues.apache.org/jira/browse/FLINK-16496
             Project: Flink
          Issue Type: Improvement
          Components: Connectors / HBase, Table SQL / Ecosystem
            Reporter: Jark Wu
             Fix For: 1.11.0


Currently, HBase sink provides 3 flush options:

{code}
'connector.write.buffer-flush.max-size' = '2mb' -- default 2mb
'connector.write.buffer-flush.max-rows' = '1000' -- no default value
'connector.write.buffer-flush.interval' = '2s' -- no default value
{code}

That means if flush interval is not set, the buffered output rows may not be flushed to database for a long time. That is a surprising behavior because no results are outputed by default.

So I propose to have a default flush '1s' interval for HBase sink or default 1 row for flush size.
