------------------------------------
Summary: ProtobufUtil seems to do extra array copying
Key: HBASE-18026
URL: https://issues.apache.org/jira/browse/HBASE-18026
Project: HBase
Issue Type: Bug
Affects Versions: 2.0.0, 1.3.2
Reporter: Vincent Poon
Priority: Minor
In ProtobufUtil, the protobuf fields are copied into an array using
toByteArray(). These are then passed into the KeyValue constructor which does
another copy.
It seems like we can avoid a copy here by using
HBaseZeroCopyByteString#zeroCopyGetBytes() ?
