Released OrientDB 0.9.22

Hi all,

many thanks to all the contributors for this new piece of software. A new version of OrientDB has been released after more than 1 month of work (and holidays).

Starting from this version you can use OrientDB as a pure GraphDB using the custom API (http://code.google.com/p/orient/wiki/GraphDatabase), by the Tinkerpop stack (Blueprints, Gremlin, Pipes, etc.) or again by using the Erlang language with the Cali project (http://github.com/dmitriid/cali).

Orient DB almost ready for the show time!

After some weekends of work I've in my hands the first version of Orient DB! I wrote a lot of Unit Tests that helped me a lot on the heavy refactoring in order to achieve the best performance than ever. The main features of Orient are:

• Full ACID: Optimistic transaction available with recovery of aborted transactions when the engine restarts. Tested with 1 billion of records even with simulated crashes during the commit phase. Pessimistic (with object-level locking) transaction in the next releases.
  
• Extremely light: less than 400kb of jar without any dependency with other libraries
• Super fast: stores 1,000,000 (yes one million) of records in 3.5 seconds on common hardware (my notebook). The KeyValue engine stores 100,000 entries indexed in 9 seconds. Lookups are so fast as memory access.
• tested up to 1 billion of records, but the limits are up to 9.223.372.036 Billions. Actually I think I'll never will be able to include this test in my Unit tests :-)
• A lot of cool features such as Asynchronous Queries, SQL language, Partitioning of data, native sharding support, and more
  
• Requires: Java5 or major and run on all the most used Operative Systems.
  

What about the license? I have no choose yet, maybe LGPL?
