Performance Questions...

Greetings ObjectDB team, All below questions assume a very large database (~1,000,000,000 objects) Q1: Two queries with a big overlap between their result sets. If I query the first and hold them in memory somehow, would that speed up the execution of the second query since many of its result objects already created and reside in memory ? Q2: Do I need to manually use strong references to such cached result objects ? or do ObjectDB exploits frequency of querying such objects and keep them in memory longer automatically somehow before GC takes place ?... on the string field could help. LIKE against patterns that start with fixed characters rather than wildcards is expected to be faster. ...
