In the process of migrating data from OnPrem to cloud, using this approach https://docs.datastax.com/en/dse/6.8/dse-admin/datastax_enterprise/operations/opsAddDCToCluster.html
I am trying to find a reliable way to check the progress and status of replication/streaming (initiated via nodetool rebuild command), with Apache Cassandra. I have seen a few suggestions , such as -
1. Monitor remaining stream via 'nodetool netstats | grep -v 100%' .
2. Run nodetool status command and check the 'Load' column - what should I expect to see?
3. Cassandra logs
Any suggestions on -
1. The options (and recommended way) to monitor the progress of replication/streaming?
2. How to reliably determine that the replication/streaming initiated by 'nodetool rebuild' command on a specific node is complete?
Appreciate any pointers!
