Subject [jira] [Commented] (HBASE-2315) BookKeeper for write-ahead logging
Date Mon, 25 Jun 2012 17:51:45 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2315?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13400722#comment-13400722
] 

Jonathan Hsieh commented on HBASE-2315:
---------------------------------------

+1 to what Jesse said.  The HLog class is relatively well encapsulated.  It already has its
own Reader and Writer interfaces (I'd probably ignore the FS argument or some how hide BK
specific stuff into a constructor), and a Metric helper class.  Excluding its constructors,
HLog only has a few hdfs-specific public methods (hsync, hflush, sync) and some public but
static methods.

> 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.
