I'm new to ObjectDB. While debugging small programs in single-step mode in NetBeans, the ODB appears to get corrupted or lost if I don't invoke close on EntityManager.

I was inteding to use TomEE+ with built-in OpenJPA and Postgres DB, initially on one master server but as it grows more master servers will be set (in different geo locations/data centers) using some data sync mechanism between them.   Now that i've met ObjectDB I want to check the option using it instead of postgres so I have few questions regarding it: ... What is the overhead of the Transaction Replayer?   Many thanks, Amit   ...
