How much faster is Redis at storing a blob of JSON compared to Postgres?
Its faster, but then, thats the point of it.Its like saying that memcache is faster than postgres.they do different things for different purposes.I still wouldn't trust redis for anything other than ephemeral storage. Most of the use cases where we use redis assume that the data will at some point go away. The places where we use postgres assume that data is permanent.Infact, we use both together, and it works really well, best of both worlds.
