Summary: Optimization : Avoid copy of key and value for tags
addition in AC and VC
Key: HBASE-11870
URL: https://issues.apache.org/jira/browse/HBASE-11870
Project: HBase
Issue Type: Improvement
Components: Performance, security
Affects Versions: 0.98.0
Reporter: Anoop Sam John
Assignee: Anoop Sam John
In AC and VC we have to add the per cell ACL tags/ visibility tags to Cells. We
get KeyValue objects and which need one backing array with key,value and tags.
So in order to add a tag we have to recreate buffer the and copy the entire key
, value and tags. We can avoid this
Create a new Cell impl which wraps the original Cell and fro the non tag parts
just refer this old buffer.
This will contain a byte[] state for the tags part.
Also we have to ensure we deal with Cells n write path not KV.
