Is it possible to do cache eviction when backplane is down #338
Comments
No that's not build in. But I guess you could implement that yourself by checking if Redis is up from time to time and then clear the cache locally? |

We have multiple services with an in-memory cache backed by a redis backplane. This is also a read through cache, so if nothing is found in in-memory or redis, then it will call an endpoint to get the information (and then put in cache).
If Redis goes down, there is potential for the individual services to perform work on stale information because the source could modify the data, but the backplane wouldnt notify because it would be down. So I was wondering if cache manager can evict when a backplane is unavailable (so our services would end up calling the readthrough)
