Hot take: We need to rethink how we build distributed systems (read: web apps). The old three tier model of client–app server-database needs to go. For basic use cases it works well enough, but as soon as you introduce complex transaction logic, or high load, it breaks.

Since the database code can't "see" the application code (and vice versa), it's very easy to introduce deadlocks, race conditions, etc. Static analysis is of little help here.

Here's my modest proposal: Stop moving data between your application and the database; instead, move the database into the application. Use a low-level store (e.g. RocksDB) for persistence and language-level primitives for concurrency control (a good use case for Rust?)

SQL is convenient for fetching data, but its concurrency primitives are lacking. What's worse, the application and the database need a shared understanding of what resources are owned by whom. This creates a lot of ugly, brittle code.

Can we replace SQL with functional programming? We take it as a given that relational languages are used to query databases, but there’s no reason we couldn’t use a language based on the lambda calculus!

2 Jan

The most important property of a query language is that we can rewrite an expression to a more efficient one, and get the same result back—this is the core of query planning. The simply typed lambda calculus supports this as it’s referentially transparent

it’s interesting that you could basically emulate type classes with explicit dictionary passing and row typing. i guess you could also implement monad transformers like this?

7 Dec 2025

apropos something @welltypedwit.ch told me back on cohost—you really want some kind of polymorphism if you’re going to implement an effect system. so you could probably use row-typed dictionaries for this as well?
