All 4500 nodes in region X would be evicted as per eviction defined in region X and all 1000 nodes in region _default_ would be evicted by the eviction time defined in region _default_. |
This is wrong. A region is just a subtree. So if you have a region defined as /a/b/c, anything you put under /a/b/c is counted towards the number of nodes in the region (e.g., /a/b/c/d or /a/b/c/e or even /a/b/c/d/e/f/g). If you have > MaxNodes nodes in the region, they will still exist in the DB, just not in memory. Your ideas around eviction are all wrong as well. Only nodes exceeding MaxNodes are evicted.

Would node c be lost? | No - eviction only REMOVES a node if it doesn't have any children. If a node has children it just empties all the data in the node, marks it as uninitialized, but keeps the node as it has a structural role to play.
