Why access IndexedDB exclusively from a Web Worker?
Tests whether you know IndexedDB in workers keeps the main thread free from serialization and transaction overhead, while recognizing that postMessage copying and request-response coordination add real architectural complexity.
Tests your grasp of main-thread isolation versus worker communication costs. A strong answer explains that IndexedDB is available inside workers per the Web Workers API, so moving storage there removes serialization and transaction contention from the UI thread. It then covers the Structured Clone Algorithm overhead in postMessage, the need for async request-response patterns to keep UI state synchronized, and strategies like command queuing or SharedArrayBuffer for large data.
