Confusion around BatchProcessor and exporterhelper

[defields923]

I recently had an issue of hitting an APM's payload limit, so I adjusted the BatchProcessor's values downward until the batch sizes were adequate, but I also noticed the exporthelper's batch sizer. I increased the BatchProcessor's values again (so the non-offending telemetry types could make use of larger batch sizes) and set the sizer to an appropriate bytes value.

Now I am seeing all the discussion around moderning the BatchProcessor, and I'm unsure if I'm doing this correctly and/or with redundancy. My assumption was that the BatchProcessor would pass the batches to the exporter which would then perform batch-splitting if necessary, but seems like the exporterhelper can simply handle the entire job of the BatchProcessor.

Is that correct? Can I retire the BatchProcessor and remove it from the pipeline if I use exporterhelper in the otlpexporter settings?

Thanks.
