My question relates to any best practices regarding Cassandra data being ingested by Decision Support type systems.
If this were Oracle I might setup a read-only standby for decision support systems to query instead of querying the online database to keep from impacting the OLTP transactions.
I'm wondering if there are any "Best Practice" type documents related to Cassandra. My thought is to create a separate DC as part of the cluster for the Decision Support systems to connect. I am wondering how other people are addressing this issue before I try to roll my own solution.
