HotBunnies 2.0.0.pre11 is released to rubygems.org.
This release is a development milestone. 2.0 focuses on usability and introduces a couple of major API improvements and features.
2.0 should be production ready from the stability perspective but has breaking API changes. Please consult the change log below before considering upgrading.
Changes Between 2.0.0.pre10 and 2.0.0.pre11
Consumer Work Pool Changes
HotBunnies 1.x used to maintain a separate executor (thread pool) per non-blocking consumer. This is not optimal and reimplements the wheel RabbitMQ Java client already has invented: it dispatches consumer methods in a thread pool maintained by every connection.
Instead of maintaining its own executor, HotBunnies now relies on the Java client to do the job.
It is still possible to override the executor when opening a connection by providing an executor factory (any Ruby callable):
1 2 3
It has to be a factory to make sure we can allocate a new pool upon connection recovery, since JVM executors cannot be cloned or restarted.
By default HotBunnies will rely on the default RabbitMQ Java client’s executor service, which has a fixed size of 5 threads.
Plans for 2.0.0 Final
There is still a few things we need to do before HotBunnies 2.0 can be declared complete:
- Further test automatic network failure recovery
- Make TLS support more configurable, ideally with the same API as Bunny 0.10
- Add logging
- API reference documentation
