**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.<br/>

**Description** Committer since 2012 and contributor since 2011. He started diving into indexes, composite indexes and many other was introduced.<br/>
He is:

1. Author of disk based storage system in OrientDB (plocal) which provides such features as durability and thread safety. Durability is achieved using write-ahead logging approach.
2. Author of "direct memory" disk cache (it is replacement of MMAP which is used underneath of all plocal components) which is based on 2Q and WOW cache algorithms.
3. Author of index system. Both hash and sbtree indexes.
4. Co-author (together with Artem Orobets) modern implementation of graph relationships.

# 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.
