Data Reply-To: Hello Cassandra-user ml, how is everyone?
Question; if we're co-locating our Cassandra and our compute application on the same nodes, are there any in-use patterns in Cassandra user (or Cassandra dev) applications for having the compute application only pull data off the localhost Cassandra process? If we have the ability to manage where we do compute, what options are there for keeping compute happening on local data as much as possible? In the best case I can imagine: If I have a KeyRange for a ColumnParent, there would be some way to know I'm going to fulfil that scan while only having each node pull it's own local data (achieve read consistency via digest). If it helps, I'd be glad to entertain options that only worked when using virtual nodes. Regards, rektide
