I'm afraid I don't have the solid answer to this obvious question: How do I get a fairly accurate count of (CQL) rows in a Cassandra table?
Does SELECT COUNT (*) FROM <table-name> actually do it? Does it really count (CQL) rows across all nodes and exclude replicated rows? Is there a better/preferred technique? For example, is it more efficient to query the row count one node at a time? And for bonus points: How do you count (CQL) rows for each node? Again, excluding replication. -- Jack Krupansky
