Hello, we can't understand why the performance of queries is not the best and the execution requires so much memory. In the implementation of our UnitTests we have used "DELETE FROM Object" to delete the database. That did not work because we often get an "out of memory" exception

Greetings ObjectDB team, The below questions assume a very large database (~1,000,000,000 objects): Q1: If my whole database is read only, is there a way to exploit this and optimize query performance ? Q2: Do LIKE operations have significant degradation on queries

we are fighting more or less since version 2.9 with the performance of our systems. We are completely unclear if indexes or statistics are really used.  sometimes a query like this takes takes around 500 ms, sometimes it takes 20 seconds  select distinct o from ObjectNode o join o

Hi, can someone share expirience with performance limits of ObjectDB especialy when quering tables with large records sets. Our issue is with tables with 100.000+ records. Everything was OK when we had few thousand records. We have a simple SELECT statement which selects from a table with 100.000
