Repository – who implements the JCR standard
http://robert.muntea.nu @rombert
Repository – Apache Jackrabbit Oak
● Open Source implementation of JCR● Developed under the Jackrabbit umbrella● Not “only” fast, but built to scale from the ground up● Aims to be a successor of Jackrabbit in a later version● #7 most active project in the ASF, according to Ohloh

Scaling – Oak topologies
TarMK● Standalone● Fast● Easy to maintain● Supports failover● No horizontal scalability
MongoMK● Horizontally scales for read and write access● Supports failover● Not as fast as TarMK
