Running several fast polling ExternalDNS instances in a given account can easily hit that limit. Some ways to reduce the request rate include: Running several fast polling ExternalDNS instances in a given account can easily hit that limit. Some ways to reduce the request rate include:
* Reduce the polling loop's synchronization interval at the possible cost of slower change propagation (but see `--events` below to reduce the impact). * Reduce the polling loop's synchronization interval at the possible cost of slower change propagation (but see `--events` below to reduce the impact).
* `--interval=5m` (default `1m`) * `--interval=5m` (default `1m`)
* Trigger the polling loop on changes to K8s objects, rather than only at `interval`, to have responsive updates with long poll intervals * Trigger the polling loop on changes to K8s objects, rather than only at `interval` and ensure a minimum of time between events, to have responsive updates with long poll intervals
* `--events` * `--events`
* `--min-event-sync-interval=5m` (default `5s`)
* Limit the [sources watched](https://github.com/kubernetes-sigs/external-dns/blob/master/pkg/apis/externaldns/types.go#L364) when the `--events` flag is specified to specific types, namespaces, labels, or annotations * Limit the [sources watched](https://github.com/kubernetes-sigs/external-dns/blob/master/pkg/apis/externaldns/types.go#L364) when the `--events` flag is specified to specific types, namespaces, labels, or annotations
