An Introduction to ETS Tables in Elixir

For example, in one of my previous articles I showed how to code a server to perform various calculations and keep the result in memory (and later we've seen how to make this server bullet-proof with the help of supervisors). There is a problem, however: if you have a single process that takes care of the state and many other processes that access it, the performance may be seriously affected. This is simply because the process ca
