Alright so punting the problems we ran into?

Last bit I'm curious about is the relative performance to main.
Something simple like counting messages over a time span would be a good indicator here.

Since we know we can easily run into issues with this, maybe we wanna hold off on the with_config variant til after this week's release?

Suggested change
pub async fn stream_with_config(&self, config: BatchConfig) -> Result<Stream<'_>, Error> {
pub async fn stream_with_config(&self, config: BatchConfig) -> Result<Stream<'_>, Error> {

@caspervonb I will follow up today with:

  1. make this private
  2. expose only batch, max bytes and heartbeats.

It's not released yet, so I would not bother with removing it, as it requires removing tests that will be needed the same day (pull with heartbeat).
