Eager load Map

I'm having an issue eager loading a nested map. I've attached @ManyToMany(fetch=FetchType.EAGER) attributes to no avail. If the map is viewed in the debugger or force iterated in the code it loads ok. The attached code attempts to replicate the scenario. Its not an exact match but is the best I could come up with without replicating the whole system. The test creates an object, persists it to a db and re-loads it. The EntityManager is closed before accesing any fields. Finally the nested map is accessed and printed to screen. ... ObjectDB Support ObjectDB - Fast Object Database for Java (JPA/JDO) ...

Failover from Master to Slave

Good morning! I am interested in ObjectDB for a client project I am currently working on. In order to evaluate your tool I would like to know if your product has the ability to failover from a Master Database to a Slave Database and then recover back to the master when the master comes back online.

Enforce Second Level cache

In my application I have an entity with few transient Collection fields, these are constantly updateing very fast and access to those fields is needs to be fast too, thus I dont persist them (also this information is temporary and doesent need to be kept).

Not sure about this but please leave your comment on this (is it really the same object kept in cache).... ...
