> It is desirable to have, in addition to the time-based flush interval, volume
> or size-based commits. E.g. a sink connector which is buffering in terms of
> number of records may want to request a flush when the buffer is full, or
> when sufficient amount of data has been buffered in a file.
> Having a method like say {{requestFlush()}} on the {{SinkTaskContext}} would
> allow for connectors to have flexible policies around flushes. This would be
> in addition to the time interval based flushes that are controlled with
> {{offset.flush.interval.ms}}, for which the clock should be reset when any
> kind of flush happens.
> We should probably also support requesting flushes via the
> {{SourceTaskContext}} for consistency though a use-case doesn't come to mind
> off the bat.
