I'm working on an output plugin for logstash and was wondering if the events that the ruby script receives can be batched (multiple events in place of the `receive(event)` method that gives a single event)?

No, you'd have to do such batching internally.

Thanks, @magnusbaeck.

Do you know if there is a `deregister` method for the output plugins that is the opposite of `register`; something similar to the `PreDestroy` annotated methods in Java? I have a resource entity that I am planning on initializing in the register method but do not want to close it every time, since the batch won't be full in one `receive` call.

I don't know, sorry.

Nm, there is a `teardown` method in the Plugin class that can be overridden for this purpose. Thanks!
