Schema changes: where in Java code are they sent?

Hello, I’m doing some research on schema migrations for Cassandra. I’ve been playing with cqlsh with TRACING ON, and I can see that a schema change like “CREATE TABLE” is sent to all nodes in the cluster. And also that “CREATE TABLE” fails if only one of my three nodes is up (with replication
