Avoid byte buffer allocations when reading a value from a Result object -----------------------------------------------------------------------
Key: HBASE-5625 URL: https://issues.apache.org/jira/browse/HBASE-5625 Project: HBase Issue Type: Improvement Components: client Affects Versions: 0.92.1 Reporter: Tudor Scurtu When calling Result.getValue(), an extra dummy KeyValue and its associated underlying byte array are allocated, as well as a persistent buffer that will contain the returned value. These can be avoided by reusing a static array for the dummy object and by passing a ByteBuffer object as a value destination buffer to the read method. The current functionality is maintained, and we have added a separate method call stack that employs the described changes. On our use case - with large map-reduce jobs - we have noticed a reduction of read time of up to 40%. -- This message is automatically generated by JIRA.
