I want to solve follow problem. For example we down one node for
maintenance reason, for a long time (30 min). Now we use TSocketPool for
polling connection to cassandra, but this poll implementation is as i think
not so good, it have a custom parameter setRetryInterval,
I'm not sure, that selecting node upon DS is a good idea. First of all every
node has values about every node, including self. Self DS values are always
better than others.
For example, 3 nodes RF=2:
N1
N2
N3
N1
0.5ms
2ms
2ms
N2
2ms
0.5ms
2ms
N3
2ms
2ms
0.5ms
We have monitored
