Hi Cassandra experts,
I am facing an issue,a node downs every day in a 6 nodes cluster,the cluster
is just in one DC,
Every node has 4C 16G,and the heap configuration is MAX_HEAP_SIZE=8192m
HEAP_NEWSIZE=512m,every node load about 200G data,the RF for the business CF is
3,a node downs one tim

use the command,but doesn’t tell us what it is exactly dose,

tombstones, they’re only removed through compaction. I
advise taking care with nodetool compact, most of the time it’s not a great
idea for a variety of reasons. Check out the above post, if you still have
questions, ask away.

client instead of relying on the coordinator assembling the results. You have
to do more work and add some complexity, but the trade off will be much higher
performance as you are removing the single coordinator as the bottleneck.
