Hi, You could easily filter/map/process the streams differently before writing them to the sinks. Building on top of my previous example, this also should work fine:
DataStream myStream = env.addSource(…).foo().bar() // for custom source, but any ; myStream.baz().addSink(sink1); myStream.addSink(sink2); myStream.qux().quuz().corge().addSink(sink3); Where foo/bar/baz/quz/quuz/corge are any stream processing functions that you wish. `foo` and `bar` would be applied once to the stream, before it’s going to be split to different sinks, while `baz`, `qux`, `quuz` and `corge` would be applied to only of the sinks AFTER splitting. In your case, it could be: myStream.filter(...).addSink(sink1); myStream.addSink(sink2); myStream.addSink(sink3); So sink2 and sink3 would get all of the records, while sink1 only a portion of them.
