Re: Help Required: Exception doing LeftOuterJoining on Multiple Streams

You can join like this in main function. Stream joinStreamInner = topology.join(streams, joinFields, new Fields("RequestId", "ColumnMapId", "FFValue", "SFValue", "TFValue"), //JoinType.mixed(JoinType.INNER, JoinType.OUTER)) JoinType.INNER) .each(new

Got the issue resolved. 1. I was not Anchoring to incoming tuple...so effectively, all the Bolts after impactBolt , were not transactional. The ack of impact bolt was causing spout's ack to be called. Proper DAG was not created. So the number I was seeing in WIP was not the true number of tuples t

The two bolts that emit and transfer 0 are most likely your persistantAggregates. They're sinks, so they don't emit or transfer anything. I forget the exact definition of capacity, but it indicates when that bolt is taking too long to process. If it's greater than one, it's a bottleneck. Its some

Executed refers to number of incoming tuples processed. capacity is determined by (executed * latency) / window (time duration). UI should give you description of those stats if you hover over table headers. On Tue, May 20, 2014, at 03:36 PM, Raphael Hsieh wrote: I reattached the previous

The two bolts which emit/transfer 0 are likely your persistentAggregate bolts. These are *sinks* so they don't logically emit/transfer tuples any farther. You can add add a name which will show up in the UI to help you see how Trident compiles into your Storm topology. .name("Aggregator 1")
