to multi racks configuration
conceptually nice to have 3 rack implementation, it does have some negative
implications when not at a proper node count.
What features are you trying to make use of with going with multirack?

Hello,
What is the general network throughput (mb/s) requirement for Cassandra?
Thanks in advance for your advise,
Justin
Nodetool drain and nodetool flush are similar commands. Both commands flush
memtable to disk. The difference is a nodetool drain will make C* stop
listening for connections.

Without knowing how you are testing things or *any* metrics whatsoever whether
it be C* or OS it’s going to be hard to help you out.

the directory structure on disk, and wants you to be at the
equivalent of the parent/data_files_directory (so if you dump your sstables at
/path/to/data/keyspace/table/, you’d want to run sstableloader from
/path/to/data/ and provide keyspace/table/ as the location).
From: Justin Sanciangco
Subject: Re: Export/Importing keyspace from a different sized cluster
You can ship the sstables to the destination (or any other server with
Cassandra binary tools installed) via ssh/rsync and run sstableloader on the
destination cluster as well.

Hello,
Assuming I can't get ports opened from source to target cluster to run
sstableloader, what methods can I use to load a single keyspace from one
cluster to another cluster of different size?
Appreciate the help...
Thanks,
Justin
