Sax > Assignee: Maximilian Michels > > FlinkTopologyBuilder cannot handle multiple input streams correctly. Instead > of union the incoming streams, it replicates the consuming bolt and each > (logical) instance processes one of the input streams. > For example: > {noformat} > final FlinkTopologyBuilder builder = new FlinkTopologyBuilder(); > builder.setSpout(spoutId1, new FiniteRandomSpout(0, 10)); > builder.setSpout(spoutId2, new FiniteRandomSpout(1, 8)); > builder.setSpout(spoutId3, new FiniteRandomSpout(2, 13)); > builder.setBolt(boltId, new MergerBolt()) > .shuffleGrouping(spoutId1) > .shuffleGrouping(spoutId2) > .shuffleGrouping(spoutId3); > builder.setBolt("sink", new BoltPrintSink(new SimpleOutputFormatter())) > .shuffleGrouping(boltId); > {noformat} > will only print the data from a single source instead of all sources. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
