The post walks through Worker lifecycle (startWorker, requestTermination), scheduling jobs with the three-parameter schedule API (TransferMode, producer lambda, job lambda), and the concept of data freezing — a runtime-level immutability mechanism that allows safe sharing across threads. Practical code examples illustrate common pitfalls like local reference failures and accidental recursive worker creation. The post also previews future topics including wrapping iOS dispatch queues and rethinking SQLite/SQLDelight design for multiplatform use. ## Full article daily.dev links to this article rather than hosting it.
