HI, Those NS collections where essentials in the first java WO mainly because at that time Java did not had real collections classes (they appeared in Java 1.8), and the name was probably kept to help porting. I did not switch to java WO at that time and maintained some objective-C apps for a l

Passing EOQualifier to a background thread

Re: fetches too often (was: weird locks) in faultWithPrimaryKeyValue

OC, If you create a new OSC, you will have no snapshot cache (I may be wrong on this), so it is the expected behaviour. I never create new OSC in my apps, why are you creating OSC like this ? The only real case I see is large report generations in background thread and even for this batching

Hi OC, Your problem description smell like an IO contention. BTW, this is not FB exclusive, all database will have the same kind of behaviour. If the is no index for the where condition, you force a table scan (read all the table rows to validate the condition). If the row data in memory, this
