I haven't used it myself, but doesn't DataNucleus have an HBase
adapter? (they support both JPA and JDO apis)

Hi,
I also think re-using JPA and the JP Quer Language is a great idea.

Hello Paul,
Looks very interesting. One consideration, though, regarding annotated
objects: wouldn't it be enormously interesting to (try to) reuse the JPA
annotations?
Another very interesting aspect on easing HBase development would be some
nifty support for necessary facets or satellites (looking for some good
term
coining here). By facets/satellites I mean the fact that some data needs
denormalization for sake of performance. Updating the annotated source
record should also update its facets/satellites spread across other tables.
Just an idea.

Subject: [Announce] HBql
Hi,
I have been working on an abstraction layer for HBase that I hope
HBase users will find helpful.
Highlights include:
* A dialect of SQL for HBase (usable in the console, scripts, and code)
* JDBC bindings
* JDBC-like bindings that support annotated objects and generics
* Query Executors that make threaded result reading simple
* Simplified filter writing for server and/or client
* Index support
HBql is a work in progress and I am open to feedback and suggestions.
I am still working on the docs, so the examples and javadocs are pretty
lame.
Have a look at: http://www.hbql.com
Cheers,
Paul
