Tim Robertson commented on BEAM-3026:
-------------------------------------
Thanks!
On reflection, I think it probably makes better sense in the
{{ElasticsearchIO.Write}} rather than the connection configuration, given batch
size control is already in there.
[It is not clear to me how the RestClient in ES is actually doing retries -
there is something in there, seemingly up to a timeout and with no pause. I
only had a quick look though]

> Currently an overloaded ES server will result in clients failing fast.
> I suggest implementing backoff pauses. Perhaps something like this:
> {code}
> ElasticsearchIO.ConnectionConfiguration conn =
> ElasticsearchIO.ConnectionConfiguration
> .create(new String[]{"http://...:9200"}, "test", "test")
> .retryWithWaitStrategy(WaitStrategies.exponentialBackoff(1000,
> TimeUnit.MILLISECONDS)
> .retryWithStopStrategy(StopStrategies.stopAfterAttempt(10)
> );
> {code}
