Conclusion
Distributed data systems is a vast field. No one knows everything. The key is continuous learning and knowing where to find information when you need it.
This appendix provides a roadmap, but your path will be unique based on your role, interests, and goals. Start with foundations, go deep in areas that interest you, and always connect theory to practice.
The journey from beginner to expert takes years, not months. Be patient, stay curious, and enjoy the learning process.
Recommended first steps:
If you haven’t already: Read “Designing Data-Intensive Applications”
Set up a local distributed system lab (Postgres + Redis + Kafka)
Join the Papers We Love reading group
Start a learning journal to track your progress
Find a mentor or study group
Good luck on your journey through the data-locality spectrum!
