Hello,
I have 2 DC 8+7 nodes Cassandra cluster with RF:2:2.
Insertion rate dropped recently.
If I stop an exact node, insertion rate goes normal.
What should be the problem?

Thank you all,
I assume, my new node is used as coordinator, since all other nodes
are under heavy write load.
I need to spare some space for hints folder.

Hello,
I have 2 dc cluster and trying to add a new node to one dc. It will
take time since total data is huge at every node.
I see waiting hints files at that joining node. What is that means?
As I understand only coordinator nodes generates hints files. Is
cluster uses this node as coordinator
Thanks Mehmet and Erick,
I don't have any monitoring other than nodetool but I manage to see
some disk errors cause exceptions.
I changed faulty disk and performance ok now.

Hello,
I manage one cluster with 2 dc, 7 nodes each and replication factor is 2:2
My insertion performance dropped somehow.
I restarted nodes one by one and found one node degrades performance.
Verified this node after problem occurs a couple of times.
How can I continue to investigate?

Hello,
Is there any way to calculate inter dc bandwidth requirements for
proper operation?
I can't find any info about this subject.
Can we say, how much sstable collected at one dc has to be transferred to other?
I can calculate bandwidth with generated sstable then.
I have twcs with one hour
I faced similar issues with different locale settings.
Could you try following command before running?
export LC_ALL=C;
