Wal

Properties

• max_slot_wal_keep_size (integer): PostgreSQL maximum WAL size (MB) reserved for replication slots. If -1 is specified, replication slots may retain an unlimited amount of WAL files. The default is -1 (upstream default). wal_keep_size minimum WAL size setting takes precedence over this.
• max_wal_senders (integer): PostgreSQL maximum WAL senders. The default is 20. Changing this parameter causes a service restart.
• wal_sender_timeout (integer): Terminate replication connections that are inactive for longer than this amount of time, in milliseconds.
• wal_writer_delay (integer): WAL flush interval in milliseconds. The default is 200. Setting this parameter to a lower value may negatively impact performance.
