Does Loki Grafana synchronize the local persistency with the persistence layer in case of non reliable connection?

Hi there, I’m considering using Loki (with a persistence layer) and Promtail as log collector and storage. In some situations, the Loki Grafana instance could not have access to the persistence layer for a discretionary amount of time (could be hours, days, or weeks).
When the connection is reestablished with the persistence layer, is Loki able to send to the persistence layer all the logs that weren’t send during the period where the connection was absent?
