==Concurrency Patterns== Concurrency is a fundamental aspect of the Elixir programming language, allowing developers to build highly concurrent and scalable applications. This page explores various concurrency patterns that are commonly used in Elixir programming. ===1. Actor Model=== The actor model is a widely adopted concurrency pattern in Elixir. It provides a high-level abstraction for concurrent programming by modeling concurrent entities as isolated actors. Actors communicate with each other exclusively through message passing, ensuring that concurrency is managed in a controlled and predictable manner. To learn more about the actor model in Elixir, read the [[Actor Model in Elixir]] article. ===2. Supervisor Pattern=== The supervisor pattern is an essential part of building fault-tolerant applications in Elixir. It involves creating a supervisor process that monitors and restarts child processes in case of failures. This pattern ensures that the application remains robust and resilient to errors. For more information on implementing the supervisor pattern in Elixir, refer to the [[Supervisor Pattern in Elixir]] article. ===3. GenServer Pattern=== The GenServer pattern is a generic server implementation that comes with Elixir's standard library. It provides a structured way to define and manage stateful processes that handle incoming requests. The GenServer pattern simplifies concurrent programming by defining a clear separation between state handling and message passing. To delve deeper into using the GenServer pattern in Elixir, read the [[GenServer Pattern in Elixir]] article. ===4. Task Pattern=== The task pattern allows for efficient parallelization of work in Elixir. It enables developers to execute multiple tasks concurrently, leveraging the underlying system resources for improved performance. This pattern is particularly useful when dealing with computationally expensive or I/O-bound tasks. Learn more about utilizing the task pattern in Elixir by exploring the [[Task Pattern in Elixir]] article. ===5. OTP Design Principles=== The OTP (Open Telecom Platform) design principles provide a framework for building robust and scalable distributed systems in Elixir. By adhering to these principles, developers can take full advantage of the built-in abstractions and behaviors provided by the OTP library, such as supervisors, event handlers, and more. For a comprehensive understanding of the OTP design principles in the context of Elixir, refer to the [[OTP Design Principles in Elixir]] article. ===6. Distributed Systems=== Distributed systems are a common use case in Elixir, as it provides excellent support for building scalable and fault-tolerant distributed applications. Understanding the various patterns and techniques for distributed systems in Elixir is crucial for building reliable and highly available applications. To explore the world of distributed systems in Elixir, check out the [[Distributed Systems in Elixir]] article. ===7. Concurrency Best Practices=== In addition to the specific concurrency patterns mentioned above, it is essential to follow best practices to ensure optimal and efficient use of concurrency in Elixir. These best practices cover topics such as process isolation, message-passing throughput, error handling, and more. For a comprehensive guide on concurrency best practices in Elixir, read the [[Concurrency Best Practices in Elixir]] article. ==Conclusion== Concurrency patterns in Elixir provide developers with powerful tools and abstractions for building concurrent and scalable applications. By leveraging the actor model, supervisor pattern, GenServer pattern, task pattern, and the OTP design principles, developers can design fault-tolerant, efficient, and distributed systems. Following best practices further ensures the optimal use of concurrency features in Elixir. {{Elixir}} [[Category:Elixir Programming Language]] [[Category:Concurrency]]
