Subject Implementing locks using cassandra only
Date Mon, 13 Sep 2010 16:46:47 GMT
I've been musing about how to implement locks using just cassandra, i.e. 
without sql db or zookeeper. I wrote up what I've come up with on the 
wiki (it's a bit too long for an email) at 
<http://wiki.apache.org/cassandra/Locking>. I'm wondering whether I've 
overlooked something, especially I'm not yet comfortable enough with the 
semantics of failing cassandra write operations to figure out whether 
these can cause problems, so I suspect some further iterations on the 
algorithm will be necessary.
