Implement deferred metadata updates #139

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
This is a step towards the btree update optimization, see issue 106. The
basic idea is after a dirty buffer is written to the on-disk journal, it is
moved to a new list, called journaled_buffers. Instead of writing the
buffer data to metadata store directly, we flush the journaled_buffers list
when the list is half full.

There is a patch posted and we need to merge the patch with Daniel's bitmap
optimization changes.
