I remember some discussions, for example if rsyslog could buffer and expose
an API, one could easily implement a plugin (say, on top of Elasticsearch)
that would enable the datastore to pull in data at its own pace.

This contrasts with the current push model, where one has to tune things
like batch sizes and retries in a way that doesn't overall the destination.
Which is not really possible, because you can't control the load generated
by queries, GC, and whatnot.

Of course the pull model has its own caveats, but it would be nice to be
able to choose what works best for every usecase.
