Hi all, I recently committed a PersistenceManager and a DataStore implementation based on Hadoop. It's in sandbox/jackrabbit-hadoop. The PersistenceManager uses Hadoop HBase, which is something similar to Googles BigTable. The data store implementation uses plain Hadoop HDFS. The performance is surprisingly good. On my machine the JCRAPITests take 40 seconds compared to 35 seconds with the default derby persistence manager.
feedback welcome. regards marcel
