Hi, I'm curious to learn about CQL's underlying implementation. I was unable to find specifics (for users/developers) in the mail archives, please hint if there is a wiki or any documentation.
CFs can be directly created using various Thrift based client implementations such as pycassa but they give access to raw cells and not high level modelling mechanisms. I tried to explore this using some test data but cells created in a namespace via cqlsh and data entered via cassandra-cli cannot be viewed interchangeable for some namespace(s). In future would it be possible to see underlying implementation/CFs of a CQL created table for example in a namespace? While I see denormalization is encouraged in various docs for Cassandra, how does CQL store denormalized data rows? Does CQL queries; - internally create links/chained CFs - have a different storage mechanism - employ data de-duplication or compacting strategy (different from that on the node/cluster), if any Should new developers use Thrift based client implementations/libs or use CQL? For achieving optimal concurrent and faster operations (reads and writes), in your experience what are some language/client-libs you would like to recommend (Scala, Go, C++, Haskell etc.?). Any details on CQL internals is appreciated. Cheers.
