Helenus is collection of Scala utilities for Apache Cassandra. Its goal is to
make interacting with Cassandra easier, in a type-safe manner, while trying to avoid introducing a complex API.

This is a demo session where we go over the asynchronous API while introducing the concepts Helenus if built upon. This is the second session out of three. You can watch the first session on the sync API here [ Ссылка ], and the third session on Akka/Pekko API here [ Ссылка ]
