Description
There are two issues with the current Kafka support
- Use of Write Ahead Logs in Spark Streaming to ensure no data is lost - Causes data replication in both Kafka AND Spark Streaming.
- Lack of exactly-once semantics - For background, see http://apache-spark-developers-list.1001551.n3.nabble.com/Which-committers-care-about-Kafka-td9827.html
We want to solve both these problem in JIRA. Please see the following design doc for the solution.
