[jira] [Created] (CASSANDRA-6697) Refactor Cell and CellName
ByteBuffer accessors to avoid garbage allocation where possible
Benedict created CASSANDRA-6697:
-----------------------------------
Summary: Refactor Cell and CellName ByteBuffer accessors to avoid garbage allocation where possible
Key: CASSANDRA-6697
URL: https://issues.apache.org/jira/browse/CASSANDRA-6697
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Benedict
Fix For: 2.1
This is a prerequisite for CASSANDRA-6692.
The basic idea is to, if unsafe is available, abuse it to modify preallocated ByteBuffers so that when they are short lived they do not need to be instantiated. Initially this will only be helpful for comparisons and lookups on the BBs, but with some modifications to the read path we should be able to reduce the need in CASSANDRA-6692 to construct BBs to pass to the native protocol (thrift may have to continue as is)
