Apollo: `/apollo/` directory structure overview

[lyletbjohnson]

Hello,

To properly use, troubleshoot, and extend the system developers need to understand the directory structure. Is there existing documentation describing how the /apollo/ code base is structured?

I also have a specific question about the purpose of the /apollo/data/core/ directory. Within my docker container, there are numerous large binary files (~1GB) for various modules, and in some cases numerous files for each module (for example core_planning.1781 and core_planning_1849).

These large files are polluting the file system, though I'm not sure what they're used for so I cannot properly clean them up.

Please help with:

1. defining what binary files in /apollo/data/core/ are used for, and
2. pointing me to existing directory structure overview documentation

You can safely delete the files under /apollo/data/core. They are not used for the main system.

Closing as this issue seems to be resolved.
