Documentation

README

OTP

Choose processes, supervision strategies, and storage for runtime concurrency and fault recovery.

The Iron Law

GENSERVER IS A BOTTLENECK BY DESIGN

A GenServer processes ONE message at a time. Before creating one, ask:

  1. Do I actually need serialized access?
  2. Will this become a throughput bottleneck?
  3. Can reads bypass the GenServer via ETS?

The ETS pattern: GenServer owns ETS table, writes serialize through GenServer, reads bypass it entirely with :read_concurrency.

No exceptions: Don't wrap stateless functions in GenServer. Don't create GenServer "for organization".

GenServer Patterns

Function Use For
call/3 Synchronous requests expecting replies
cast/2 Fire-and-forget messages
