James Taylor commented on HBASE-7692:
-------------------------------------
I'm investigating moving Phoenix to use Orderly. It's very similar to what
we're doing today, but has more functionality with a cleaner API.
[[email protected]] The Writable stuff is used as a bytes pointer, not as a
client/server data exchange mechanism. Phoenix uses them the same way. It's
just a lightweight way to have an offset/length into a byte array. You can also
reset the byte[],offset,length on an instance which prevents having to
re-instantiate a new one every time (unlike the java.nio.ByteBuffer)
The permutations are useful. One set of them instantiate a new object on
deserialize (for Java native object types like Integer and Long), while the
others reuse a byte buffer to hand you back what was deserialized. Both are
useful under different circumstances. We'll try to use the latter.
It'd be great if this could be packaged as a separate maven module such that
Phoenix can depend on it since it's still on the 0.94 branch.

> The current Bytes utility class works, but produces output that does not
> maintain the native sort ordering of the input value. This results in, for
> example, a negative value that does not necessarily sort before a positive
> value. HBase should provide a canonical implementation of such a
> serialization format so that third-parties can reliably build on top of
> HBase. This will allow an implementation for HIVE-3634, HIVE-2599, or
> HIVE-2903 that is compatible with similar features in Pig.
