Description

What is the problem you are trying to solve?

When running a big instance of mimir v3 we found ourselves with throughput of 0.5GB per second (2000000 active series)

Which solution do you envision (roughly)?

Can it be possible to enable by flag the option to push and pull compressed data into the kafka between the distributor and the ingestor?

Have you considered any alternatives?
