>          Components: Connectors / HBase, Table SQL / Ecosystem

>             Fix For: 1.12.0

> 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.
