Committers have reached the Guru Level OrientDB certification. They coordinates updates, patches, new tasks and answer actively to the Google Group. They talk in a private Mailing List to take decision all together.
**Description** Luca is the original author of OrientDB product and the main committer. In order to handle indexes in efficient way Luca has created the new MVRB-Tree algorithm (it was called RB+Tree but another different algorithm already exists with this name) as mix of Red-Black Tree and B+Tree. MVRB stands for Multi Value Red Black because stores multiple values in each tree node instead of just one as RB-Tree does. MVRB-Tree consumes less than half memory of the RB-Tree implementation mantaining the original speed while it balances the tree on insertion/update. Furthermore the MVRB-Tree allows fast retrieving and storing of nodes in persistent way. He is member of the Sun Microsystems [JDO 1.0 Expert Group (JSR#12)](http://www.jcp.org/en/jsr/detail?id=12) and JDO 2.0 Expert Group (JSR#243) for the writing of JDO standard.**Company** [NuvolaBase Ltd](http://www.nuvolabase.com)

# Contributors
Contributors are all the people that contribute in any way to the OrientDB development as code, tests, documentation or other. They talk in a private Mailing List with all the other committers and contributors and are updated on changes in internal stuff like binary protocol. One time patch doesn't make you a contributor, but if you're developing a driver or you sent more patches then you are a candidate to figure in this list.
