Yeah, but I really do not bite your argument.
When you are reduced to do manual memory management and fight the GC of your language, maybe you should simply not use a language with GC in the first place.
They are right to use rust ( or C/C++) for that. It's not for nothing that redis (C) is so successful in the LRU domain.

And still ScyllaDB (C++) is able to completely destroy Cassandra in term of AVG latency [0]
