-----------------------------------------
Summary: Check if size of object being added to RowCache and
KeyCache is bigger than cache capacity
Key: CASSANDRA-16904
URL: https://issues.apache.org/jira/browse/CASSANDRA-16904
Project: Cassandra
Issue Type: Improvement
Components: Local/Caching
Reporter: Josh McKenzie
Assignee: Josh McKenzie
We don't check if the size of an object being added to the RowCache/KeyCache
itself exceeds the max configured size of the cache.
For instance, if a RowCache object is ~5GB due to IndexInfo objects, but the
cache is configured to have a max capacity of 100MB, we will still add the 5GB
object into the cache and then need to wait for the eviction thread in the
cache to come around, realize we're over capacity, and remove the object from
the cache.
We could check the size of the object with jamm and ensure it's smaller than
the max size of the cache. If it exceeds the size of the cache don't cache it
at all.
