> In the Put API, we have addImmutable()

>  /**
>    * 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.
