So at a given point of time if there are 4500 nodes are there in memory, and the application tries to put 1000 more nodes in the same region, would these nodes be put in db. SO there would be 4500+1000 = 5500 nodes in db and only 4500 nodes in memory? The in-memory nodes are a subset of what's in the DB. Although, if you use activation/passivation then they are disjoint sets. The MaxNodes is for the in memory configuration. Yes to your last question.
