What is asab?

ASAB is an asynchronous Python microframework, designed to be robust, configurable, and easily extensible. It’s particularly useful for building complex distributed applications that require a high degree of concurrency and fault tolerance. Here are some key aspects:

• Asynchronous Programming: ASAB is built upon Python's asyncio library, leveraging asynchronous programming paradigms. This allows for non-blocking I/O operations, improving performance and scalability, especially in network-bound applications. See more about Asynchronous%20Programming.

• Microframework Architecture: ASAB provides a minimal set of core functionalities, enabling developers to build applications by composing modular components. This promotes code reusability, maintainability, and flexibility.

• Configuration Management: ASAB provides a sophisticated Configuration system. It supports various configuration sources, such as environment variables, configuration files (e.g., YAML, JSON), and command-line arguments. The configuration can be dynamically reloaded at runtime.

• Metrics and Monitoring: ASAB includes built-in support for collecting and exposing application metrics. This is crucial for monitoring application performance, identifying bottlenecks, and ensuring system stability. Check about more at Metrics%20and%20Monitoring.

• Logging: ASAB provides a comprehensive logging framework that allows you to capture detailed information about application events. This logging can be configured with different logging levels and destinations. Get more at Logging.

• Service Discovery: It is common to deploy ASAB based applications in containerized and clustered environments. As such ASAB supports service discovery protocols like Consul and provides out of the box integration. Find more info at Service%20Discovery.

• Extensibility: ASAB is designed to be highly extensible. Developers can create custom components, such as processors, connectors, and web services, to integrate with existing systems and add new functionality.

• Fault Tolerance: ASAB is built with fault tolerance in mind. It provides mechanisms for handling errors, retrying failed operations, and ensuring application availability.
