Subject Re: Decommission faster than bootstrap
Date Fri, 23 Aug 2013 02:48:32 GMT
We are using 1.0. Our observation is that if you are using secondary index,
building secondary index after streaming is time consuming. And the
bootstrap needs to wait for the process of building secondary indexes to
complete.

I am not sure if this also applies to 1.1/1.2. You could set the log level
to debug to observe what is really going on when a node is bootstraping.
