Hi
We had a cluster with 3 Nodes with Replication Factor 2 and we were using read
with consistency Level One.
We recently added a 4th node and changed the replication factor to 3, once this
was done apps reading from DB with CL1 would receive an empty record, Looking
around I was surprised to le
You have RF=3 and both read & write CL=1, which means you are asking
Cassandra to give up strong consistency in order to gain higher
availability and perhaps slight faster speed, and that's what you get.
If you want to have strong consistency, you will need to make sure (read
CL + write CL) > R
request will actually return a correct result?
Thanks
