Hello everyone,
We have just released GenStage 0.10.0 with an important bug fix if you were using the BroadcastDispatcher with a selector. It also has an improvements to Flow, both in terms of API and internals.
The CHANGELOG is shown below:
Enhancements
- Add
Flow.group_by/3andFlow.group_by_key/3as conveniences aroundFlow.reduce/3 - Add
Flow.map_values/2for mapping over the values in a key-value based state - Add
Flow.take_sort/3that efficiently sorts and takes the top N entries
Bug fixes
- Ensure BroadcastDispatcher sends demand to itself when custom selector discards events
- Ensure flows started with
Flow.start_link/2properly terminate if producers terminate - Ensure flows exit locally instead of relying on linked processes exits. With this change,
Flow.run(flow)andEnum.to_list(flow)no longer start stages linked directly to the caller but does so through a supervisor
Where Next?
