Hi, We are using cassandra 3.10 in a 10 nodes cluster with replication = 3. MAX_HEAP_SIZE=64GB on all nodes, G1 GC is used. We have about 60 keyspaces with about 80 tables in each keyspace. We had to delete three tables and two materialized views from each keyspace. It began to take more and more time for each next keyspace (for some keyspaces it took about 30 minutes) and then failed with "Cannot achieve consistency level ALL". After restarting the same repeated. It seems that cassandra hangs on GC. How that can be solved?
Thanks
