Loki Deletion of Tenant Data

We are using Loki in the Single Store mode (boltdb-shipper index type). I have 2 questions related to data deletion in this mode:

  1. What is the recommended way of deleting all data belonging to a tenant (e.g. functionality similar to Cortex delete_tenant API: Deletion of Tenant Data from Blocks Storage | Cortex)?
    Should it relay on (manual) deletion of the tenant data in the storage bucket?

  2. What is the recommended way of automated data retention?
    The Documentation at Retention | Grafana Labs mentions that Retention in Loki is achieved through the Table Manager. Is that true for Single Store mode as well?
