If you have been around the Elixir ecosystem for a while, you have probably heard about “ETS”.
ETS stands for Erlang Term Storage. It’s a storage engine that is built into OTP, and is therefore available in Elixir through the interoperability with Erlang.
ETS is a key / value store, and so you can think of it as pretty much the same as Redis. But because ETS is built right into OTP, you get it for free, without having to rely on a third-party dependancy!
In today’s tutorial we are going be looking at using ETS in Elixir.
