I have two Data Centers, each one with replication factor 3.

Will write with CL.ALL block until data is stored in both DCs (6 nodes, or 3 + 1)?
I would assume, that it blocks until all 3 replicas in local DC has acknowledged successful write.

I would like to have something like CL.ALL_LOCAL, which stores data on all replicas in single DC, so I can read with CL.ONE. The idea is, that write blocks until all replicas in single DC has persisted data, and following read will have high probability to read fresh data

    There isn’t currently a consistency level that provides what you are describing. The closest is LOCAL_QUORUM which will return after a quorum of nodes in the local datacenter respond.

    You can file a ticket on jira to add this functionality if you would like.
