Thanks for the pointer! Please note that @glommer is talking about the classic secondary index implementation in Cassandra, which is very simple but also broken. I don't know the details but we probably did have "half-ready" code for that. We decided against going forward with it because Cassandra had already moved to SASI (which is also much more complex). As I said, we're currently focusing on materialized views, and tacking secondary indices after that. Btw, I highly recommend subscribing to our user mailing list or engaging on Github for questions and comments about features. You'll get better and up-to-date answers there. Update: reading @glommer's reply carefully, he explicitly says that he's unsure if we'll move forward with that specific implementation: "_if_ we do implement it, it should land in our main version in a couple of weeks" (emphasis mine).
