Summary: Slight improvement of StoreScanner.optimize
Key: HBASE-14539
URL: https://issues.apache.org/jira/browse/HBASE-14539
Project: HBase
Issue Type: Sub-task
Reporter: Lars Hofhansl
Assignee: Lars Hofhansl
Priority: Minor
While looking at the code I noticed that StoreScanner.optimize does not some
unnecessary work. This is a very tight loop and even just looking up a
reference can throw off the CPUs cache lines. This does safe a few percent of
performance (not a lot, though).
