By "partitions" I assume you refer to "partition keys".
Generally, the more partitions keys, the better. Having more partition keys
means your data generally is spread out more evenly across the cluster,
makes repairs run faster (or so I've heard), makes adding new nodes more
smooth, and makes it less likely that you are at hitting tombstone limits.
Also, 100 partition keys in a Cassandra table is nothing. If you don't have
more partition keys than that, Cassandra might not be the right fit.
