Mahadev konar commented on HBASE-2315:

 here is some documentation that might help you understand the architecture of BooKkeeper:


this documentation has been improved in 3.3 (not branched yet), so you can checkout

> BookKeeper, a contrib of the ZooKeeper project, is a fault tolerant and high throughput
write-ahead logging service. This issue provides an implementation of write-ahead logging
for hbase using BookKeeper. Apart from expected throughput improvements, BookKeeper also has
stronger durability guarantees compared to the implementation currently used by hbase.
