Jonathan Ellis commented on CASSANDRA-3921:
-------------------------------------------
I'm not sure what the right fix is. We could invalidate the row, but that
means a big compaction could wipe out the row cache entirely, which is worse.
Should we just wontfix this?

> Key: CASSANDRA-3921
> URL: https://issues.apache.org/jira/browse/CASSANDRA-3921
> Project: Cassandra
> Issue Type: Bug
> Affects Versions: 0.8.0
> Reporter: Jonathan Ellis
> Priority: Minor
> Fix For: 1.1.0
>
>
> Compaction calls removeDeletedInCache, which looks like this:
> {code}
> . public void removeDeletedInCache(DecoratedKey key)
> {
> ColumnFamily cachedRow = cfs.getRawCachedRow(key);
> if (cachedRow != null)
> ColumnFamilyStore.removeDeleted(cachedRow, gcBefore);
> }
> {code}
> For the SerializingCache, this means it calls removeDeleted on a temporary,
> deserialized copy, which leaves the cache contents unaffected.
