Confusion regarding emqx-rule-engine
daadu opened this issue · comments
emqx-web-hook and emqx-rule-engine have overlapping use cases. For example processing all messages published by web server can be done by both the plugin.
Can some from @emqx clarify the following:
- Which one the plugin is recommended for it?
- Performance wise which is better?
- Does any one of it implement "fire and forget" mechanism for sending messages to web server instead on syncronously waiting for response?
- Since it looks redundant which one of the plugin will be in active development, is there any plan to deprecate
emqx-web-hookin favour ofemqx-rule-engine?
No, these two plugins are fundamentally different, Even if they can deal with some kind of special user scenarios.
The emqx_web_hook focuses on forwarding the Broker event to a webserver directly. It won't modify the event's data and information. Just forwarding it. This is the biggest difference between and rule engine.
The emqx-rule-engine emphasizes the Rules. It can change the structure of a message, or pick up some field data for an event in your requirements.
It's more powerful than emqx-web-hook. But emqx-web-hook is necessary for some simple or fundamental user scenarios.
Which one the plugin is recommended for it?
it depends on your requirement. If you need simply forwarding, emqx-web-hook is advisable.
Performance wise which is better?
There should be no apparent difference
... "fire and forget" mechanism ...
They don't support now. We have a plan at v4.2.0
is there any plan to deprecate emqx-web-hook ...
Nope.
@HJianBo Thanks for the clarify. I guess this should be documented somewhere - in emqx blogs or tutorial.
Thanks. Closing this issue.
Re-opening since this is added to https://github.com/emqx/emqx-web-hook/milestone/53. milestone
