[jira] [Created] (HBASE-16658) Optimize UTF8 string/byte conversions

binlijin created HBASE-16658:
--------------------------------

             Summary: Optimize UTF8 string/byte conversions
                 Key: HBASE-16658
                 URL: https://issues.apache.org/jira/browse/HBASE-16658
             Project: HBase
          Issue Type: Improvement
            Reporter: binlijin
            Priority: Minor


String/byte conversions may take either a Charset instance or its canonical name. One might think a Charset instance would be faster due to avoiding a lookup and instantiation of a Charset, but it's not. The canonical string name variants will cache the string encoder/decoder (obtained from a Charset) resulting in better performance.
