------------------------------------
Summary: Automalically flush a BufferedMutator after a timeout
Key: HBASE-19486
URL: https://issues.apache.org/jira/browse/HBASE-19486
Project: HBase
Issue Type: Improvement
Components: Client
Reporter: Niels Basjes
Assignee: Niels Basjes
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.
