Jeff Dean and Sanjay Ghemawat are amazing engineers and this code is (/was?) nice.

To avoid some confusion, this is only the "distributed" part. The actual store is handled by the https://github.com/google/leveldb library.
This may have been mentioned already, but the open-sourced LevelDB codebase is great. Original authors are Jeff Dean and Sanjay Ghemawat, so you know it's going to be really well written.

LevelDB is a widely used C++ project, written by the same people who wrote core parts of Google Search 20 years ago:

There was some discussion on the very same for an Ask HN[0]. Copying my comment from there I've found the google/leveldb[1] source code to be immensely educational, authored by Jeff Dean and Sanjay Ghemawat. The implementation of leveldb is similar in spirit to the representation of a single Bigtable tablet[2].
