They're an implementation detail for crash recovery, not something you can use directly. I can only find them described in documentation for very old versions of prometheus: https://prometheus.io/docs/prometheus/1.8/storage/#crash-recovery The database format changed completely in 2.x, but the code still includes WAL checkpoints.
If you want something you can access, look at snapshots: https://prometheus.io/docs/prometheus/latest/querying/api/#snapshot -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
