Subject [jira] Updated: (CASSANDRA-801) The Key Cache should be configurable by absolute numbers
Date Wed, 17 Feb 2010 00:15:28 GMT


Stu Hood updated CASSANDRA-801:

    Attachment: 0002-Update-config-values.patch

Converts KeysCachedFraction to KeysCached, using the same semantics as RowsCached.

Since we cache keys on a per-sstable basis, the number of Keys cached can still grow considerably
if you have many, many sstables, but perhaps we can address that in a separate issue.

> Just like the row cache, the key cache should be configurable by absolute numbers (not
just a fraction). It would be nice to configure it by either memory size or entries (like
the row cache).
