Mapped By Fetch is very Slow

Well ! I think i pointed out a HUGE performance issue with mapped-by attribute (yeah again :( ). Here is the test case : 1- Create 100 000 entities with for each 1 entity with @OneToOne(mappedBy attribute) 2- Retrieve only 10 000 for testing 3- Wait ... On my AMD FX 8350, it took 60s Now, go the MyEntity class and remove "mapped-by". You obtain 1 second max of query fetch. ... Maximum file size: 32 MB 0 ...

Possible issue with timestamps

Hi, If I query doing something like: select c from CDI c where c.creationDate > {ts '2012-03-29 11:00:00} and c.creationDate < {ts '2012-03-29 12:00:00'} the test fails. Its ONLY for 12:00:00. When I started digging I found that if I queried 00:00:00 to 00:25:00 and then did 12:00:00 to 12:25:00 I got IDENTICAL results. For some reason 12:00:00 is being treated the same as 00:00:00. All other hours seem to be fine. ... Maximum file size: 32 MB 0 ...

Hi again,   Honestly, I'm fairly new with JPA2 Criteria queries - but as far as code effort goes, it has saved me a bit of pain. I'm writing a dynamic query builder (only 1 level deep for basic entities) - but  even though I get most queries to work, I am getting the following error. This is using Criteria with a combination of LOWER/UPPER - NOT LIKE: ... Maximum file size: 32 MB 0 ...

Indexing a field results in internal Exception

I have an application that I have been converting from JPA/MySQL to JDO/ObjectDB and I have hit a problem with indexing. An index on a String field is required to give good performance but if I add the @Index annotation to the field I eventually end up with an ObjectDB internal exception.  This is reproducible, as is the program running to completion (slowly) if I remove the @Index annotation.  Is there anything I can look for that might result in this exception? ...
