[jira] [Created] (CASSANDRA-7096) Evaluate murmur hash of token only once

Benedict created CASSANDRA-7096:
-----------------------------------

             Summary: Evaluate murmur hash of token only once
                 Key: CASSANDRA-7096
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-7096
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Benedict
            Assignee: T Jake Luciani
            Priority: Minor
             Fix For: 3.0


Every bloom filter lookup we perform recalculates the murmur hash for the token. I propose we extend DecoratedKey for the purposes of reads only, and attach the full murmur hash to it so that we can pass these directly to the bloom filter.
