Do L1, L2 and L3 each have to be backed by different Cassandra clusters or can I have them backed by the same Cassandra cluster?

You can have them backed by the same Cassandra cluster but then you couple the availability of these locations to the availability for QUORUM writes to a single Cassandra cluster. If this is ok for you, this shouldn't be a problem. It is recommended (but not necessary) that each location uses its own keyspace.

Can I mix and match event log types within a Location?

Yes, a replication endpoint is configured with a logFactory that can be used to create different log types (i.e. LevelDB or Cassandra) for different log names.

Do L2 and L4 have to have different Cassandra clusters backing them?

See my first answer.

Thank you for the information. I was operating under the assumption that we could do as you have described but wanted to validate that.
