-------------------------------------
Summary: Save object creation for scanning with FAST_DIFF encoding
Key: HBASE-14628
URL: https://issues.apache.org/jira/browse/HBASE-14628
Project: HBase
Issue Type: Bug
Reporter: Lars Hofhansl
I noticed that (at least in 0.98 - master is entirely different) we create
ByteBuffer just to create a byte[], which is then used to create a KeyValue.
We can save the creation of the ByteBuffer and hence save allocating an extra
object for each KV we find by creating the byte[] directly.
In a Phoenix count\(*) query that saved from 10% of runtime.
