Jimmy Xiang commented on HBASE-5958: ------------------------------------ By the way, is it an option to use reflection to access the private constructor? If so, I can have a wrap method to use the private constructor, or the original copyFrom if the private constructor is not accessible. Reflection has overhead of course. > Replace ByteString.copyFrom with new ByteString() > ------------------------------------------------- > > Key: HBASE-5958 > URL: https://issues.apache.org/jira/browse/HBASE-5958 > Project: HBase > Issue Type: Improvement > Components: performance > Affects Versions: 0.96.0 > Reporter: Jimmy Xiang > Assignee: Jimmy Xiang > Fix For: 0.96.0 > > > ByteString.copyFrom makes a copy of a byte array in case it is changed in > other thread. > In most case, we don't need to worry about that.
