Benedict created CASSANDRA-7244:
-----------------------------------
Summary: Don't allocate a Codec.Flag enum value array on every read
Key: CASSANDRA-7244
URL: https://issues.apache.org/jira/browse/CASSANDRA-7244
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Benedict
Assignee: Benedict
Priority: Minor
Fix For: 2.1 rc1
Attachments: 7244.txt
In QueryOptions.Codec.Flag.deserialize() we call Flag.values(), which
constructs a copy of the Enum array each time. Since we only use this lookup
the enums, and since it happens _often_, this is pretty wasteful. It seems to
make a few % difference to throughput.
