> Currently, JDBC sink provides 2 flush options:
> {code}
> 'connector.write.flush.max-rows' = '5000', -- default is 5000
> 'connector.write.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 JDBC sink or default 1 row for flush size.
