---------------------------------------
Summary: Cache key references might cause OOM on incremental repair
Key: CASSANDRA-11739
URL: https://issues.apache.org/jira/browse/CASSANDRA-11739
Project: Cassandra
Issue Type: Bug
Reporter: Paulo Motta
Assignee: Paulo Motta
Attachments: heapdump.png
We keep {{SSTableReader}} references for the duration of the repair to
anti-compact later, and their tidier keep references to cache keys to be
invalidated which are only cleaned up by GC after repair is finished. These
cache keys can accumulate while repair is being executed leading to OOM for
large tables/keyspaces.
Heap dump attached.
