The write activity every 5 minutes is standard Postgres checkpointing, the default value for checkpoint_timeout is 5 minutes. This is not limited to RDS.
Background processes like vacuum and analyze also write to WAL.
- ritmatter 5y agoThanks, I didn't know that. Why do you think the Debezium docs call out this behavior specifically for RDS (https://debezium.io/documentation/reference/stable/connectors/postgresql.html#postgresql-wal-disk-space https://debezium.io/documentation/reference/stable/connector...)? I'm wondering if there is any difference for RDS vs other hosting methods.
