- I was just looking to build a database similar to Redis for practice, and thought Elixir's ETS and OTP would be useful.

- Just learning more about databases while building a Redis alternative.

- It appends operations, the same ones you write to the TCP client and when loading them, just runs those one by one. I will still add some optimizations for e.g. repetitive commands.

- I haven't thought much about it yet, feel free to start a discussion in the GitHub repository to further talk about that.

- Probably not crash the server but return more useful errors and use Elixir's OTP features.

Glad to hear that you liked the project!
