In a recent customer issue we observed that during a decomission, when we were streaming snapshots to a new node 90% of snapshots were ingested into L0. The expectation is that Pebble should be capable to ingest all incoming snapshots into a lower level. The goal of this ticket is perform an investigation to understand why does Pebble behave this way and come up with a proposal for improving the snapshot ingestion path.
