Agree that flushIntervalInMs is dependent on other flag but if we think
from user perspective both have different meaning.
> Add Time-Based Flushing to Writer Bolt

> 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.
