aws-kinesis-client v0.4.0.0 Release Notes

  • 🚀 This release contains breaking changes.

    • Replaced the internal use of MonadError with proper open-world exceptions. The exposed operations which may throw exceptions have been adjusted to return m (Either e a); resolves issue #17.

    • [Producer] Implemented a cleaner shutdown routine policy: previously, the producer would stay alive indefinitely until the thread on which it was created is killed. Now, the producer is shut down immediately once the scope of withKinesisProducer exits, at which point the queue will be flushed according to a configurable (and optional) timeout. Resolves issue #19.

    • [Producer] Restructured the monolithic error sum types into many smaller types to better support the standard mode of use for error handling.

    • 🚚 [Consumer] Removed unused ConsumerError type.

    • [Consumer] Changed batch size to use Natural type rather than Int.

    • [Producer] Parameterized the implementation by an arbitrary queue structure; by default, the producer's message queue is now implemented using TBMChan to avoid a bug in TQueue which causes live-locking under very heavy load.

    Other non-breaking changes:

    • 👍 [Producer] A better, more reliable implementation of consuming the input queue in chunks.

    • ✂ Removed dependencies on either, errors, hoist-error, stm-conduit; added dependency on enclosed-exceptions.

    • Increased lower bound on monad-control to 1.0 (for hygienic purposes).
