Hi,
Is it possible to get/predict how much time it will take for *nodetool -pr *to
complete on a node? Currently in one of my env (~800GB data per node in 6
node cluster), it is running since last 3 days.
Regards,

Options: Assuming model and configurations are good and Data size per node
less than 1 TB (though no such Benchmark).
1. Infra scale for memory
2. Try to change disk_access_mode to mmap_index_only.
In this case you should not have any in memory DB tables.
3. Though Datastax do not recommended and
k trace - anything else deserves a bug report.

Hi,
Need input on cassandra upgrade strategy for below:
1. We have Datacenter across 4 geography (multiple isolated deployments in
each DC).
2. Number of Cassandra nodes in each deployment is between 6 to 24
3. Data volume on each nodes between 150 to 400 GB
4. All production environment has DR se

Hi,
Is there any CLI or API which I can use to validate hint files checksum is
correct?
Reason to ask for such utility/CLI - We are doing rolling upgrade for
Cassandra in Google cloud. As approach we bring down nodes, take snapshot
backup, upgrade and bring node up. During this process hint file
