Table snapshot: use C*2.1 pattern #111

Not compatible with C*2.0

rhardouin commented 7 years ago

Snapshotting a table doesn't work with C*2.1 because of UUID (it works for whole keyspace). If we want to handle both 2.0 & 2.1 naming we can drop the -:

table_glob = '%s*' % snapshot_table

But then we can have troubles if a table is a substring of another one e.g.:

users
users_by_email

Let's say we want to backup users only, then we would end up with both tables because of users*. So we have to make a choice, keep using glob and drop C*2.0 support or scan dirs with a regex.

one option would be to make this configurable (eg. --cassandra-2.0)
