exactly once semantics #29
Description
Hi
Does the way river integrate with kafka allow for exactly once semantics? I'm trying to understand if the data could be lost or duplicated while moved from kafka into ES.
My guess is that it is impossible for data to be lost.
For example spark integrates tightly w kafka to provide exactly once semantics: https://databricks.com/blog/2015/03/30/improvements-to-kafka-integration-of-spark-streaming.html
