Subject [VOTE] Release Apache Mavibot 1.0.0-M2
Date Tue, 29 Oct 2013 09:23:13 GMT
Hi !

This is the second release of Apache Mavibot, the MVCC BTree in Java !

This milestone is an improvement on the way we handle data in the BTree,
more specifically when we reach the memory limits. We switch from using
WeakReference to favor a cache, which guarantee way better performances.

We also split the API into two different BTree : 
o in-memory btrees
o managed btrees

The Managed BTree use the disk to store the data. We also optimized the
way we manage tree traversal when we have a lot of page being swapped
out of the cache, avoiding a lot of useless deserialization of values
and keys, leading to a net gain in performance.

ApacheDS has already been tested with Mavibot 1.0.-M2-SNAPSHOT, and it
offers pretty good performances compared to JDBM, with a 2.5x faster
addition. 

So let's vote now !
