Introduction to MySQL Adapter Development for Ecto with Elixir

The article by Wojtek Mach introduces the first part of a series about creating a MySQL adapter for Ecto using Elixir. The focus is on setting up the initial connection and authentication with a MySQL server. Specific steps include creating a user without a password for simplicity, running MySQL in Docker for multi-version testing, and using IEx to connect through `:gen_tcp`. The process involves reading and interpreting MySQL packets, bitstring syntax, and handling “Initial Handshake Packet” and “Handshake Response”. It’s a practical guide to getting started with low-level MySQL integration in Elixir.
