Subject [jira] Created: (CASSANDRA-678) row-level cache
Date Thu, 07 Jan 2010 00:36:54 GMT
row-level cache
---------------

                 Key: CASSANDRA-678
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-678
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
            Reporter: Jonathan Ellis
            Assignee: Jonathan Ellis
            Priority: Minor
             Fix For: 0.9


We have a key cache but that doesn't help mitigate the expensive deserialization of the actual
data to return.

Adding a row-level cache should be fairly simple using a ConcurrentLinkedHashMap<String
[key], ColumnFamily> structure.  (We will only cache whole rows at a time, since already
know how to query on those in-memory.  This limits us to CFs full of narrow rows but that
is a common enough use case to be worth tackling if it can be done simply enough.)
