batch processor and aggregation

[overmeulen]

Hello,

I'm new to opentelemetry and I need your help.
I'm trying to aggregate metrics inside my Collector Gateway.
For that I'm using the metricstransform processor.
I realized (as it was very explicitly stated in the doc) that it doesn't aggregate metrics coming from different Collector Agents.
The thing is I don't understand why it doesn't work if I add a batch processor before the metricstransform processor in my Collector Gateway.
Isn't it supposed to batch all the metrics coming from the different Agents into a single batch and then run the metricstransform processor on it ?

Thanks,
Olivier
