Mahadev konar commented on HBASE-2315:
--------------------------------------
todd,
here is some documentation that might help you understand the architecture of
BooKkeeper:
http://hadoop.apache.org/zookeeper/docs/r3.2.2/
this documentation has been improved in 3.3 (not branched yet), so you can
checkout
http://svn.apache.org/repos/asf/hadoop/zookeeper/trunk/docs/bookkeeperOverview.html
and read that as well.
hope this helps.
> BookKeeper for write-ahead logging
> ----------------------------------
>
> Key: HBASE-2315
> URL: https://issues.apache.org/jira/browse/HBASE-2315
> Project: Hadoop HBase
> Issue Type: New Feature
> Components: regionserver
> Reporter: Flavio Paiva Junqueira
> Attachments: HBASE-2315.patch, zookeeper-dev-bookkeeper.jar
>
>
> 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.
