Hi there,

I am learning how to use the [MongoDB output pluing](https://www.elastic.co/guide/en/logstash/current/plugins-outputs-mongodb.html#plugins-outputs-mongodb-common-options) and trying to understand how to delete a document in a collection.

I was wondering if this is supported.

The alternative I can think of is to have a `tombstone` flag that tells Mongo that the document is deleted plus subsequent garbage collection.

Thank you all in advance for any answer!

The [code](https://github.com/logstash-plugins/logstash-output-mongodb/blob/c38344c7b25e665be9bcffbb76598db5e8d2a69f/lib/logstash/outputs/mongodb.rb#L106) always calls either insert\_one or insert\_many. I do not see a way to do a deletion.

There is a PR in `logstash-output-mongo` and I am working on one myself.

Had to learn ruby 😃 But this is definitely possible!
