I have a simple topology with one spout and one bolt...with parallelism set to 1 for both. While conducting some volume tests, I noticed there is a two-fold throughput increase when ackers are turned off.
Any insight in to why Ackers incur such a huge overhead will be helpful in tuning the same. Right now I have set the "topology.ackers.executors" is to default which is null. In that case, I see 1 acker per worker. Even that adds a huge overhead.
