One limitation of Rust macro is that it can only access code token, not actual type information. When macro sees a type `X` macro can never be sure whether it's `&str` as Rust allo…

The optimistic concurrency control that reads multiple shards cannot use simple CAS. It probably needs to do something like two-phase committing

Thanks for reply. So in my understanding: - The transactions that only touch one shard is simple - The transactions that read multiple shards but only write shard can use simple op…

In real-world business requirements it often need to read some data then touch other data based on previous read result. It violates the "every transaction can only be in one shard…

This video criticizes Rust using perfect solution fallacy. Critizing a useful thing just because it's imperfect. https://en.wikipedia.org/wiki/Nirvana_fallacy

We are in the down season.

There are two kinds of slowness. One is trying hard while getting no visible result. Another is procrastination. The article refers to the first
