min-connections-maintenance-timeout

This parameter controls how long Radiator waits for a PostgreSQL min-connections maintenance probe before treating it as failed.

Set it inside a PostgreSQL backend server block.

Accepts duration units such as 1s, 500ms, or 2s.

Default: 1s

server "primary" {
    url "postgresql://radiator:secret@db.example.com:5432/radiator";
    min-connections 2;
    min-connections-maintenance-timeout 1s;
}

This setting only affects servers where min-connections is greater than 0.

If the timeout is too short, slow connection establishment can be treated as a failure. If it is too long, recovery from unreachable servers becomes slower.

See connections and min-connections and min-connections-maintenance-retry-interval.
