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 factor = 3). I’ve been trying to find the Java code where the schema migration is sent to the other nodes in the cluster, to understand what the requirements are for successfully applying the update. E.g.: is QUORUM consistency level applied? I spent an hour looking through the Java code last night, with no luck. I thought this code would be in StorageProxy.java, but I have not found it there, or in any of the other classes I looked at. Any pointers would be appreciated. Thanks, best regards, Rich
