I am doing small queries and they take much longer than I expect, i.e.: Get the total number of entries Get 25 consecutive entries (i.e. 0-25) Get one specific entry On average each query needs 4 to 5 minutes to return a result.

We tried earlier to modify this relationship but it breaks the database. We reported this problem ...

Unfortunately, we will receive an OutOfMemory exception because the objects are kept in the first level cache of ObjectDB. In the forum thread http://www.objectdb.com/database/forum/921 on post #4 you wrote, that ObjectDB should support very large transactions in further version. Can you implement it that ObjectDB used temporary files? Bug Version: 1.04 Priority: Critical Status: Fixed Replies: 27 Type:  Bug ...
