> I'm working on several projects where we are doing stream / event type
> processing instead of batch type processing. We mostly use Apache Flink and
> Apache Beam for these projects.
> When we ingest a continuous stream of events and feed that into HBase via a
> BufferedMutator this all works fine. The buffer fills up at a predictable
> rate and we can make sure it flushes several times per second into HBase by
> tuning the buffer size.
> We also have situations where the event rate is unpredictable. Some times
> because the source is in reality a batch job that puts records into Kafka,
> sometimes because it is the "predictable in production" application in our
> testing environment (where only the dev triggers a handful of events).
> For these kinds of use cases we need a way to 'force' the BufferedMutator to
> automatically flush any records in the buffer even if the buffer is not full.
> I'll put up a pull request with a proposed implementation for review against
> the master (i.e. 3.0.0).
> When approved I would like to backport this to the 1.x and 2.x versions of
> the client in the same (as close as possible) way.
