Jetpack DataStore - protocol buffers storage solution

on YouTube ↗19m

" summary

Jetpack DataStore replaces SharedPreferences with an async, transactional storage that uses Kotlin coroutines & flows for nonblocking reads and writes. Two implementations exist: Preference DataStore for key/value pairs (edit is a suspend function) and Proto DataStore for typed objects using protocol buffers plus a generated serializer and schema for full type safety. A built-in SharedPreferences migration moves old data automatically; updateData performs atomic read‑modify‑write.
