Xiang Li updated HBASE-14882:
-----------------------------
Description:
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 family, qualifier and value are still being
copied locally to create kv.
Hopefully we should provide an API that truly uses immutable family, qualifier
and value.
