Subject Re: Hbase ORM any one interested?

I guess this is a popular idea. :-)

I've built what I call an "object -> cloud" mapping that works with  
Hbase. It stores everything as json so if you manage to build a  
binding for it (through Hbase's thrift interface) it should work with  
any language.  I say "object -> cloud" because the idea of the  
software is to expose to other people some of the features and  
limitations of a column oriented database, not just have them use the  
same old relational models and end up getting nasty surprises later.

It was designed for read-heavy, interactive applications and  
prototyping. For the latter, it has a simple "disk file" version so  
people can get the app working before sending it to an hbase cluster.   
It allows you to have multiple searchable "columns" by building it's  
own indexes off to the side.  It tries, for example, to expose the  
idea that this is not cheap by making people select the searchable  
items in their data.

If folks are interested, please drop me a note. I  need to make a case  
that this software should be open sourced and several emails from  
people about how they might use it would help.


ps. If anybody has an hbase cluster that has some idle time I'd love  
to get some performance numbers... my current unemployment makes  
renting EC2 nodes a bit out of bounds...
