Managing parallelism using coroutines

on YouTube ↗45m

" summary

Shows concrete patterns: uses Kotlin coroutines to run parallel network and DB work with uses Retrofit and Room, times where parallel launches cut two-second totals to one, and how structured concurrency, supervisorJob and cancellation semantics, and dispatcher choices actually behave in production. Includes error cases that crash vs ones that retry, test approaches with runBlocking, a caching+timeout pattern that keeps the UI responsive, and production NYT examples so it demonstrates what was built and whether it worked.
