Performance in large transactions

Hello, we have a performance problem when we use a large transaction. Let's do exactly the same in several transactions the ObjectDB works much faster. In our use case, we create many new entities and between the creations we call a select query. The execution of the query becomes slower at each iteration. (In the query, we search for an item of type Entity2. However, there is only one entity.)   Pseudocode for the fast and the slow solution FAST: ... java.util.ArrayList (which is untrackable) a user can build a new entity object with the trackable version. Using this method is ...

Connection is closed Caused by: java.io.EOFException

I am getting this exception on a regular basis, after a period of time of repeating the same code execution.  I don't understand why.  I restart the DB server and my code works again for another period of time until same exception is encountered again.  I cannot pin down a pattern e.g. after a certain period of time,  because the time  periods between exceptions are not regular, although frequent.  Any test case  I use will pass most of the time but will fail after an undetermined period. ... exception on the client side was changed, so starting next build it will be same as the more meaningful exception that you found in the ...

Speed of queries that return many objects

Hi, I have a DB of 146MB - with 1_000_000 elements. Loading the contents (objectDB query in java) takes about 10sec. I am using a recent MacBook (SSD blabla - disk I/O speed is about 400MB/sec - according to blackMagicTest app for mac) - so I was expecting the query to take less than one sec (146/400 = 0.35sec.. + some overhead). I was wondering if this kind of speed is "normal", or if this is something I should investigate.

evictAll() behavior

I'm writing a multi-user drawing tool, using objectdb as the central store.  When a user press F5, I want to pick up all the changes from the database.  So, I call evictAll() in the following ways: pmf.getDataStoreCache().evictAll();  // the factory pm.evictAll();                                 // the persistence manager A couple of questions about this: 1. the first evictAll() seems to be clearing the L2 cache -- is this correct 2. the evicts only work when they are done inside a transaction -- is this specified in the JDO spec?...
