provided family, qualifier, value without copying
[ https://issues.apache.org/jira/browse/HBASE-14882?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15403138#comment-15403138 ]

----------------------------------
HI Stack, thanks for the comment!
Do you mean to use an anonymous internal class which implements Cell and resides in Put?

> In the Put API, we have addImmutable()
> {code}
> /**
> * See {@link #addColumn(byte[], byte[], byte[])}. This version expects
> * that the underlying arrays won't change. It's intended
> * for usage internal HBase to and for advanced client applications.
> */
> public Put addImmutable(byte [] family, byte [] qualifier, byte [] value)
> {code}
> But in the implementation the row, family. qualifier and value are still being copied locally to create kv.
> Hopefully we should provide an API that truely uses immutable family, qualifier and value.
