You might want to review this blog post on supporting dynamic columns in CQL3, which points out that “the way to model dynamic cells in CQL is with a compound primary key.”
See: http://www.datastax.com/dev/blog/does-cql-support-dynamic-columns-wide-rows -- Jack Krupansky From: Maciej Miklas Sent: Monday, May 19, 2014 11:20 AM To: user@cassandra.apache.org Subject: CQL 3 and wide rows Hi *, I’ve checked DataStax driver code for CQL 3, and it looks like the column names for particular table are fully loaded into memory, it this true? Cassandra should support wide rows, meaning tables with millions of columns. Knowing that, I would expect kind of iterator for column names. Am I missing something here? Regards, Maciej Miklas
