> a Redis caching layer and a complex custom lookup scheme
Bane of my life. A few gigs ago, they had a global Redis cache, a Redis cache per server, an in-app cache, and then MySQL. Needless to say, there were many, MANY bugs that came down to cache coherency and race conditions between them.
[edit: it was a global Redis, not clustered.]
