I'm running a nodetool rebuild to include a new DC in my cluster.
My config is:
DC1, 2 nodes per rack (2 racks), 70gb each node
DC2, 2 nodes per rack (1 rack), 90gb each node
DC3, 2 nodes per rack (1 rack) (*THIS IS THE NEW DC*)
What I did was get the 2 nodes in DC3 up and running with bootstrap=false,
and then ran a rebuild using DC2 as a parameter.
However, when I started, the load in both new nodes rapidly increased to
1.4GB, according to nodetool status. And then it was slowly increasing for
4 hours, in a 10mb basis. Then, suddenly, 1 node had 49.5GB and the other
In the instance logs, I have only stream messages from when I've started
My point is, is it normal to Cassandra accumulate this amount of data and
then send it? I was hoping that it was more of a gradual and incremental
