429 RESOURCE_EXHAUSTED message when Redis is unavailable

Hi there,
I was running some tests with redisquota adapter. I have Redis running in my cluster and my test service has rate limit applied.

When I make Redis unavailable I am getting 429 RESOURCE_EXHAUSTED from my service. Is there any way how to change this behavior to not to apply msg rate limit when Redis is down?

I don’t want to write own adapter and it seems to me, that this should be configurable.

Thanks.
