             Summary: Improve retrying in ElasticSearch client
                 Key: BEAM-3026
                 URL: https://issues.apache.org/jira/browse/BEAM-3026
             Project: Beam
          Issue Type: Improvement
          Components: sdk-java-extensions
            Reporter: Tim Robertson
            Assignee: Reuven Lax


Currently an overloaded ES server will result in clients failing fast.
I suggest implementing an backoff type 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}
