Also for testing purposes, you can send only one replica set to the Test DC.
For instance with a RF=3 and 3 C* racks, you can just rsync/sstableload one
rack. It will be faster and OK for tests.
Best,

wrapper around nodetool/sstableloader that I’ve been running for the past few
years – https://github.com/AppliedInfrastructure/cassandra-snapshot-toolsAlways
seemed to work well for these kinds of scenarios… Never really had to think
about where SSTables were on the filesystem, etc. Mike From: Justin Sanciangco

Subject: Re: Export/Importing keyspace from a different sized cluster Something
like that, depending on your version (which you didn’t specify). Note, though,
that sstableloader is notoriously picky about the path to sstables. In
particular, it really really really wants a directory structure that matches
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

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. From: Justin Sanciangco <jsancian...@blizzard.com>

Subject: Export/Importing keyspace from a different sized cluster 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
