effect-concurrency

Use Effect.all with a concurrency option to run independent tasks in parallel. It preserves robust error handling by modeling failures with Cause trees and supports modes like 'either' or 'validate' to manage error propagation safely across concurrent operations.

Structured concurrency coordinates parallel fibers, manages background work, and ensures resource safety. You need it for bounded processing, graceful shutdown, and robust error handling across asynchronous tasks to prevent unmanaged background operations and memory leaks.

Use fork types like forkChild, forkDetach, or forkScoped to manage supervised, global, or scoped background tasks. These primitives ensure resource safety and enable graceful shutdown by controlling fiber lifecycles within defined scopes.

Fiber-based concurrency uses synchronization primitives like Deferred, Semaphore, and Queue to coordinate tasks and apply backpressure. This ensures reliable parallelism by managing task flow and preventing overwhelming downstream resources.

Yes, use the 'validate' mode with Effect.all to run independent tasks in parallel and collect all errors. This differs from default fail-fast behavior by accumulating failures into a Cause tree, allowing comprehensive error reporting.
