Store info about free BTree nodes on disk

Created: 11/Jul/08 01:34 PM   Updated: 26/Sep/08 11:33 AM
Component/s: Native Sail
Affects Version/s: None
Fix Version/s: 2.2


 Description   
The NativeStore's BTrees currently determine if there are any free nodes by crawling the entire tree and flagging the ones that are crawled. This is a very time consuming process for large indexes, which needs to be repeated each first time in a session that a structural modification to the BTree is required. This process can be sped up by storing the free node info on disk when the BTree is closed.
