Hi ,
I am trying to experiment with the recovery time of a riak node using
bitcask storage after a crash .
I was able to find some information about that in this page (which is
for Innodb though)
http://wiki.basho.com/Recovering-a-failed-node.html which is more
about Innodb .
Upon Reading bitcask paper i found it uses hint file to constructs in
memory mapping , so it should not ideally take more than few mins to
reconstruct data after crash . Please throw some light on this .
I got this thread dump when i tried the steps outlined in the above link.
