The ScyllaDB team is delighted to announce ScyllaDB Rust Driver 0.5.0,
an asynchronous CQL driver for Rust, optimized for Scylla, but also compatible with Apache Cassandra!

Cool, ever growing open-source stats:

  • over 38k downloads on crates;
  • over 300 GitHub stars!

=== Notable changes ===

  • Client-side timeouts are here! Request timeout can be set for a session, or, with higher granularity, for a specific statement.
  • CachingSession implementation was simplified, it no longer reimplements separate repreparation logic.
  • Continuous integration tests are now run on a 3-node cluster, increasing the test coverage for whole classes of distributed errors.
  • CQL logic was extracted to a separate scylla-cql crate, so that it can be reused by other projects.
  • Debug was implemented for a few important structs - Session, PreparedStatement, etc.
  • In certain cases, retry policy will not properly react on an error returned from the database and not retry - this is now fixed.
  • Materialized view info is now included when fetching database schema.
  • TracingInfo now has a neat helper function, which returns the list of nodes that took part in processing given request
  • DowngradingConsistency policy is implemented (although it's only recommended for very specific use-cases).
  • It's now possible to obtain a list of replicas that are most likely to serve given statement,
    by computing owner nodes of a particular token, if this information is available.
  • Clone implementation for PreparedStatement got slimmed, now it does not copy an unnecessary list of tracing ids.

Also, the usual stuff: fixes, speedups, amendments, doc updates and example updates were all applied.

Congrats to all contributors and thanks everyone for using our driver!
