Hi
What are the design approaches I can follow to ensure that data is consistent
from an application perspective (not from individual tables perspective). I am
thinking of issues which arise due to unavailability of rollback or executing
atomic transactions in Cassandra. Is Cassandra not suitab
Hi,
I'm using allocate_tokens_for_keyspace and num_tokens=32 and i wan't to extend
the size of some clusters.
I read in articles that for num_tokens=4, one should add more 25% of cluster
size for the cluster to become balanced again.
1. For example, with num_tokens=4 and already have 16 n
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.

Hello,
I would like to copy some data from one cassandra cluster to another
cassandra cluster using the CQLSH copy command. Is this the good approach
if the dataset size on the source cluster is very high(500G - 1TB)? If not
what is the safe approach? and are there any limitations/known issues to
I don’t know if it’s the OPs intent in this case, but the response latency
profile will likely be different for two clusters equivalent in total storage
but different in node count. Multiple reasons for that, but probably the
biggest would be that you’re changing a divisor in I/O queuing statist

I’m curious – is the scaling needed for the amount of data, the amount of user
connections, throughput or what? I have a 200ish cluster, but it is primarily a
disk space issue. When I can have (and administer) nodes with large disks, the
cluster size will shrink.
