Concurrency Options

Effect provides powerful options to manage the execution of effects, offering control over the concurrency of operations. Explore the `concurrency` option, a key factor in determining how many effects can run concurrently. This concise guide delves into sequential execution, numbered concurrency, unbounded concurrency, and the flexible inherit concurrency option. Learn to harness these options to optimize the performance of your Effect programs and tailor the concurrency behavior to your specific use cases.

Fibers

Discover the power of fibers in Effect, providing a lightweight and efficient way to manage concurrency and asynchronous tasks. Learn the fundamentals of fibers, their role in multitasking, and how they contribute to responsive applications. Explore the creation of fibers, their lifetimes, and various forking strategies, gaining insights into structured concurrency and daemon fibers. Unravel the intricacies of when fibers run, enabling you to optimize their execution and harness the full potential of concurrent programming in Effect.

Introduction to Effect's Interruption Model

Explore the intricacies of Effect's interruption model, a crucial aspect in concurrent application development. Learn the nuances of handling fiber interruptions, including scenarios such as parent fibers terminating child fibers, racing fibers, user-initiated interruptions, and timeouts. Delve into the comparison between polling and asynchronous interruption, understanding the advantages of the latter in maintaining consistency and adhering to functional paradigms. Gain insights into when fibers get interrupted, providing examples and scenarios for a comprehensive understanding of this vital feature.

Deferred

Explore the power of `Deferred` in Effect, a specialized subtype of `Effect` that acts as a one-time variable with unique characteristics. Discover how `Deferred` serves as a synchronization tool for managing asynchronous operations, allowing coordination between different parts of your code. Learn common use cases, including coordinating fibers, synchronization, handing over work, and suspending execution. Dive into operations such as creating, awaiting, completing, and polling `Deferred`, providing practical examples and scenarios to enhance your understanding of this powerful tool.

Queue

Explore the lightweight, in-memory `Queue` in Effect, designed for composable and transparent back-pressure. Learn about its fully asynchronous, purely-functional, and type-safe characteristics. Delve into basic operations, creating different types of queues, and efficiently adding and consuming items. Discover how to shut down a queue gracefully and handle exclusive capabilities with offer-only and take-only queues. Enhance your understanding of `Queue` and leverage its power for seamless coordination in your asynchronous workflows.

PubSub

Dive into the world of `PubSub` with Effect, a powerful asynchronous message hub that facilitates seamless communication between publishers and subscribers. Learn the core operations, explore different types of pubsubs, and discover the optimal scenarios for their use. Understand the versatile operators available on pubsubs, from publishing multiple values to checking size and gracefully shutting down. Gain insights into the unique qualities that set pubsubs apart and their equivalence to queues in various scenarios. Elevate your understanding of `PubSub` to enhance your asynchronous workflows.

Semaphore

Discover the power of semaphores in Effect, a synchronization mechanism that regulates access to shared resources and coordinates tasks in an asynchronous and concurrent environment. Delve into the fundamental concept of semaphores, learn how they function in Effect, and explore real-world examples showcasing their application in controlling asynchronous tasks. Gain insights into precise control over concurrency using permits and understand how semaphores elevate your ability to manage resources effectively.
