We have our own internal codebase of Cassandra at Digg. But we are using those above patches until we have the vector clock work cleaned up, that patch will also goto jira. Most likely the vector clock work will go into 0.7, but since we run 0.6 and built it for that version, we will share that patch too. -Chris On Apr 6, 2010, at 10:17 AM, S Ahmed wrote: > Chris, > > When you so patch, does that mean for Cassandra or your own internal > codebase? > > Sounds interesting thanks! > > On Tue, Apr 6, 2010 at 12:54 PM, Chris Goffinet <goffi...@digg.com> wrote: > That's not true.
