My personal opinion is that I don't see a widespread need for more capacity given horizontal scaling and servers that can already exceed 1 Tbyte of DRAM; bandwidth is also helpful, but I'd be concerned about the increased latency for adding a hop to more memory. Ford, et al., “TCP

In the MySQL open source ecosystem, we have only two consolidated ways to perform sharding — Vitess and ProxySQL. Let’s see the write operations with 24 and 64 threads: We get a gain of ~33% just using sharding, while for latency, we do not have a cost. Do not go for the last shiny things just because they shine.
