----------------------------------------
Summary: Optionally prune CDC segments if consumer fails to
consume them fast enough
Key: CASSANDRA-17001
URL: https://issues.apache.org/jira/browse/CASSANDRA-17001
Project: Cassandra
Issue Type: Improvement
Reporter: Dinesh Joshi
Assignee: Yifan Cai
Current CDC implementation blocks writes if the CDC segments have filled up.
This makes sense for some use-cases. In other cases it would be beneficial for
C* to prune the CDC segments if they haven't been consumed. This will prevent
blocking of writes. With this change we will introduce a flag to prune CDC
segments much like a circular buffer. This will prevent the writes being
blocked.
