Hello Nicolas, I am not familiar with endeca so I cannot speak specifically to that product. What I can do is provide you with a list of reasons that brought me to use OrientDB with my web2py project.
This is a far from exhaustive list but rather some of the OrientDB specific features which happened to fit my project best: - Ability to have schema-full, schema-mixed, schema-less data all in one DB. The combination of Document db and Graph db is a big deal because you can evolve your data over time without breaking/slowing/ hurting/rebooting/running 2 month long queries to add one column of data to the running system. - SQL syntax is both familiar to me and can be easily adapted to DAL. - GREMLIN graph traversal language bundled in is able to be combined with SQL sytax allowing for very powerful queries on your graph. -- Yes Gremlin is available for many other graph dbs but none others have SQL syntax that can be combined with Gremlin. - Apache 2.0 license is very liberal. Free for any use. - Built in clustering for distributed/high availability setups. -- Neo4j has clustering too but only under commercial license as I understand it. - Initial testing (more required) of my application revealed OrientDB pulling relevant data in 1-7 ms versus 80-90 in a traditional RDBMS. - Luca Garulli is all over all forums Massimo style with helpful answers and rapid development. - Pro support and training is available. - web2py, OrientDB, Gremlin have been the 3 most informative and helpful communities I have ever encountered = great for long term usage. For more complete information go to http://www.orientechnologies.com the home of OrientDB. Do go there and click the Documentation button to learn more about OrientDB. The wiki is very informative.
