-------------------------------------------------------------
The previous assignee seems to have dropped this task. Absent objections, I
will take it over.
However, after discussion with [~james.sirota], we agree that this issue should
be subsumed into METRON-322.
Thus, closing this ticket without resolution. Please see METRON-322 for
further work on the topic.

> Add Time-Based Flushing to Writer Bolt
> --------------------------------------

> Key: METRON-227
> URL: https://issues.apache.org/jira/browse/METRON-227
> Project: Metron
> Issue Type: Bug
> Reporter: Domenic Puzio
> Assignee: Matt Foley
>
> We need to change the BulkMessageWriterBolt and BulkWriterComponent to use
> time-based flushing when writing data to Elasticsearch or Solr.
> Currently, we set a batch size, and the Writer waits for that number of
> tuples to build up; however, Storm has a timeout value that prevents it from
> waiting for too long. If the Writer does not get the batch size before the
> timeout, then it recycles the tuples through the topology. In addition, Storm
> only allows so many pending messages that have not been acked - if too many
> messages are waiting for the bulk Writer, then it will recycle them through
> the topology. This is not desired behavior and directly impacts the
> performance of this Writer. We would like to be able to specify a unit of
> time for which the topology would flush, writing the data it's currently
> holding to Elasticsearch or Solr even if the batch size is not met.
