It can offer an advantage over the built-in caching, but it depends on your exact access patterns. For example, if you are running ClickHouse on multiple servers and accessing the same reference data, it's more efficient to cache that data in a centralized location (like Regatta) instead of on the disk of each individual instance.
Philosophically, our goal is to build a standard that can be used in these kinds of applications moving forward, so that application developers don't need to build streaming over and over again and users don't need to learn how to configure each individual systems' caching.
