Does anyone know about this "Oldest Replication Slot Lag" in AWS RDS? What does it represent?
I have a PostgreSQL instance on RDS (with Logical Replication switched on) for transferring data from PostgreSQL DB to S3 bucket (in CSV form) using AWS Data Migration Service. The graph of "Oldest Replication Slot Lag" is too high on this instance. and also Transaction Log Disk Space goes up too.
