1- Is there any particular reason other than consistency in the state regarding at least once processing of messages for forcing to emit anchored tuples.
2- What are the downsides of emitting tuple without anchoring? *Error:* Caused by: java.lang.UnsupportedOperationException: Bolts in a stateful topology must emit anchored tuples. at org.apache.storm.topology.BaseStatefulBoltExecutor$AnchoringOutputCollector.emit(BaseStatefulBoltExecutor.java:162) ~[storm-core-1.1.0.jar:1.1.0] -- Thanks & Regards, Anshu Shukla
