stack commented on HBASE-2315:
------------------------------
Thanks you for this work Flavio. Before going to the patch, a few of us, when
BookKeeper showed up first, had this notion of writing HBase WAL to a BK
Ensemble but we never did any work on it because we figured it just wouldn't be
able to keep up.
For example, posit a smallish hbase cluster of 3-5 nodes each taking on writes
of 10bytes-1MB of edits at rates of 100-5k writes a second. Would BK be able
to keep up? What if is was a 10-20 node cluster? What you think?
> 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.
