ObjectDB Clustering VS Hadoop Hbase

The Hbase is an open source distributed database on Hadoop, it is robust regardless of the performance problem. The ObjectDB cluster may be a distributed database, I guess. But I dont know whether it has only one entry, or each node has an entry. Could you please explain the difference between Hbase and ObjectDB clustering? TIA   ...

problem with lazy loading - unittest project attached

hi, i'm still testing objectdb together with spring-data-jpa. i made a test which should simulate 4 requests 1. save entity 2. read an existing entity, add onetomany relation 3. read an existing entity, add another onetomany relation 4. read entity, get relations. i have the feeling this is not the optional way to test this, because of the differnt transaction behavior. the test is not transactional, but the spring repository methods are. ...

Pessimestic Locking doesn't release when application unexpectedly terminates.

Hi, We have several services in our app framework that we want to use a cluster singleton. Our approach to this was to use Objectdb's pessimestic locking. This seems to work, but if the owner of the current pessimestic lock abruptly quits without releasing the lock it doesn't get released.    Is there anyway the server can detect that a client (lock owner is no longer connected) and therefore release the lock ?   Thank you   Paul Newman ...

Out of Memory - Slow leak?

This is a continutaion of Issue 61 - unfortunately it doesnt seem that the fix in 2.2.9_03 has fixed the problem. The scenario is still the same: I have two "producer" processes which insert messages into an objectdb "queue" database running with an objectdb server process. I have one "consumer" process which reads messages from the queue database and inserts these into an embedded "normal" objectdb database. This is the process which has generated the OOM exception. ... ObjectDB Support ObjectDB - Fast Object Database for Java (JPA/JDO) ...
