This is really interesting! The performance looks impressive. I’ve always struggled with the Redis/MySQL two-tier architecture because they are two completely different systems. Porting an application is always tricky due to API incompatibility, and maintaining consistency between the two is a huge hassle. If there’s any issue on the cache side (like performance jitters or a few servers going down), the DBMS part can quickly get overwhelmed. This kind of cascading failure is a common problem in distributed systems. There are some great discussions on this topic over at https://danluu.com/cache-incidents/. BTW, although the formatting is a bit rough, it's a great read for anyone interested in caching. Back to the topic, I always hoped that new advancements in database systems can alleviate or eliminate this problem, your work seems to be on the right track.
