The ScyllaDB team is pleased to announce ScyllaDB Rust Driver 1.6.0,
an asynchronous CQL driver for Rust, optimized for ScyllaDB, but also compatible with Apache Cassandra!

Some interesting statistics:

  • over 6.5M downloads on crates!
  • over 666 GitHub stars!

Changes

New features / enhancements:

  • Introduced “Client Routes Routing” (with some preceding internal and testing preparations in #1590), which is a feature allowing the use of driver in deployments with mechanisms like AWS PrivateLink (#1582).
  • Exposed more configuration options for sockets opened by the driver (#1577).
  • durable_writes field was added to Keyspace struct (#1578).
  • :warning: Our MSRV was bumped to 1.88 (#1602).
  • :warning: Removed address translation workaround, because the root cause was fixed in Scylla a long time ago (#1606).

Bug fixes:

  • Session::query_iter / Session::execute_iter now correctly refresh driver metadata (if enabled in session config) after a DDL statement is executed using those APIs (#1579).
  • Fixed a bug in implementation of result metadata ID extension. This bug prevented reading the results of some special statements (like LIST ROLES of) if they were executed as prepared statements (#1581).

Documentation:

  • Fixed Github links displayed on crates.io by making them absolute instead of relative (#1572).
  • Updated Scylla theme to 1.9 (#1584) and then to 1.9.2 (#1608).
  • Fixed improper total_connections metric docstring (#1586).
  • Bumped sphinx-multiversion-scylla to 0.3.8 (#1605).

CI / developer tool improvements:

  • Add various Scylla flags to our docker-compose.yml to make tests run faster (#1574).
  • Clippy fixes (#1576).
  • Book tests are now executed along other doctests, instead of using mdbook test (#1591).
  • Our MSRV check CI pipeline no longer checks examples/ folder (#1594).
  • Introduced a tool to print sizes of our error types (#1597).
  • Recently Scylla stopped creating a default superuser cassandra:cassandra, which broke our tests. Fixed that by using flags to explicitly create the superuser (#1601).
  • Small fix for a test incorrectly handling proxy finish result (#1603).
  • Added wait_for_connection and inject_event_to_cc methods to our testing proxy (#1610).
  • Explicitly disable tablets for our one SingleStrategy tests, because Scylla started to throw errors on SimpleStrategy keyspace creation with tablets (#1611).
