This is a starting point for C++ solutions to the

["Build Your Own Kafka" Challenge](https://codecrafters.io/challenges/kafka).

In this challenge, you'll build a toy Kafka clone that's capable of accepting

and responding to APIVersions & Fetch API requests. You'll also learn about

encoding and decoding messages using the Kafka wire protocol. You'll also learn

about handling the network protocol, event loops, TCP sockets and more.

**Note**: If you're viewing this repo on GitHub, head over to

[codecrafters.io](https://codecrafters.io) to try the challenge.

# Passing the first stage

The entry point for your Kafka implementation is in `src/main.cpp`. Study and

uncomment the relevant code, and push your changes to pass the first stage:

```sh

git commit -am "pass 1st stage" # any msg

git push origin master

```

That's all!

# Stage 2 & beyond

Note: This section is for stages 2 and beyond.

1. Ensure you have `cmake` installed locally

1. Run `./your_program.sh` to run your Kafka broker, which is implemented in

   `src/main.cpp`.

1. Commit your changes and run `git push origin master` to submit your solution

   to CodeCrafters. Test output will be streamed to your terminal.
