stack commented on HBASE-2315:
------------------------------
One other thing, can you speak to the following?
HBase gets dissed on occasion because we are 'complicated', made up of
different systems -- hdfs, zk, etc. -- so adding a new system (bk to do wals)
would make this situation even worse?
In our integration of zk, we did our best to hide it from user. We manage
start up and shutdown of ensemble for those who don't want to be bothered with
managing their own zk ensemble. Would such a thing be possible with a bk
cluster?
> BookKeeper for write-ahead logging

> 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.
