Level 2 cache not hit in @ManyToOne

Hi! I have 2 entities: User and Item, both @Cacheable. Item has @ManyToOne private User user. Level 2 JPA cache is activated and it works ok for find by id (tested by changing data in explorer and reading in my app). Problem 1: find by id on Item it's good, it hits the cache, but not for its field "user". "user" is loaded each time from the DB (tested by changing data in explorer and reading in my app). "user" should also be taken from L2 cache, shouldn't it? Otherwise...it's a huge performance hit. ... and it works ok for find by id (tested by changing data in explorer and reading in my app).

Object DB In memory : without Filestore

Hello, I raised this question earlier as well, we want to explore if I can run the ObjectDB completely in Memory ? (without any writes to Disk, it's okay to loose the data if the node is down ). I think that will give the best performance. The reason we are exploring is restoring state is possible for us through replaying the logs, however we want easier data structures which is really good with ObjectDB along with Concurrency controls and transaction mgmt. Let us know if it is possible to run the Object DB completely in memory without disk storage. #1 2013-10-04 07:31 Hello, I raised this question earlier as well, we want to explore if I can run the ObjectDB completely in ...

ObjectDB's Database Doctor Incorrect Error Report

Am I reading this correctly?  It seems that Doctor is telling me that one of my objects is missing.  Looking at the database with ObjectDB's Database Explorer though seems to show that the reference to the object is good and that the object does indeed exist.   Output from Doctor Diagnose and Doctor Repair is attached.  So are the two databases and screenshots of Explorer showing the reference to the object and the existence of the object. ...
