The Cassandra cluster I operate consists of two datacenters.
Most data has a TTL of 14 days and stores one data for each data center. (NetworkTopologyStrategy, datacenter1: 1, datacenter2: 1)
However, for a few days ago, only the datacenter1 disk usage is increasing rapidly.
There is no change in nodetool cleanup on each node of datacenter1.
How does this happen? What can I do?
I would appreciate your advice.
Thank you in advance.
