We have created 6 node Cassandra Cluster. 1 node is search node, others are Cassandra nodes. We are using Datastax Enterprise.
Currently, no application is using that cluster so there isn't any application that inserts data to cluster. But Ops Center says, we are inserting 2 GB of data every day. When we look at column families, there isn't any row in column families.
How can this be happen?
Is there any idea?
