Luca Garulli

Luca Garulli

Chief Executive Officer, Founder

Luca is the original author of the OrientDB product and the main committer. He started working with storage algorithms in 1998 and created the first production-ready version of OrientDB in early 2010 after 17 years of experience working with other DBMSs. In order to handle indexes in the most efficient way, Luca created the new MVRB-Tree algorithm (it was originally referred to as the RB+Tree but another different algorithm already exists with that name) as a mix of the Red-Black Tree and B+Tree algorithms. MVRB stands for Multi Value Red Black because it stores multiple values in each tree node instead of just one. MVRB-Tree consumes less than half the memory of the RB-Tree implementation, maintains the original speed when balancing the tree on insertion/update, all while allowing fast retrieval and storage of nodes in persistent mode. Luca is a member of the Sun Microsystems JDO 1.0 and 2.0 Expert Groups that wrote the JDO standard. He has also published various tech articles in Technet, Computer Programming, IoProgrammer, and Week.it magazines.
