Hi Andy,
Internode encryption is not possible without downtime prior to Apache
Cassandra 4.0.As there is no optional option before 4.0 under
server_encryption_options, If you try to enable it, cassandra running
on version 3.x wouldn't start as the property isnt available.
optional is only avai
I wouldn't say it's good approach for that size. But you can try dsbulk
approach too.
Try to split output into multiple files.

Hi All,
I started seeing the opscenter stopped opening and taking long time.
It is throwing lot of GC allocation error as follows.
I tried increasing the Xmx and Xms values but its not helping.
Can someone suggest on this ?

Is there a way to find top 10 tables with top 10 sstables per read and
top 10 tables with top tombstones per read in Cassandra?
As In Opscenter everytime we have to select the tables to find whats
the tombstones per read. There are chances that we might miss

Run the repair with -pr option on each node which will repair only the

Please do try COPY TO commas to dump the data with csv or any other

You have to download the Prometheus HTTP jmx dependencies jar and download
the Cassandra yaml and mention the jmx port in the config (7199).
Run the agent on specific port" on all the Cassandra nodes.
After this go to your Prometheus server and make the scrape config to
metrics from all clients.

Hi All,
I am trying to do compaction on the same node. But getting the below error
any suggestion on this.

nodetool -h testserv1 -p 9160 compact

Yes, if your intension is to decommission a node. You can do that by
clicking on the node and decommission.

Hi Jens,
If you decommission a data center, The data residing in the Data Center
which you are planning for decommission has to be balanced to the nodes of
the other data center satisfying RF. Hence Repair is required.

Bring down the second node using nodetool removenode or decommission
Add the node with num_tokens and run the nodetool repair.
At last run the nodetool cleanup on both the nodes (one after the other)
Observe after some time using nodetool status.
