Deployment and Operations This category is for questions and discussions on deploying services, operating services, the metrics and tracing for services, integration with CI/CD tools. Testing A category for questions and discussions about testing services and about using the SDK test kit. Event Sourced Entities Event Sourced Entities are components that persist their state using the Event Sourcing Model. Instead of persisting the current state, they persist all the events that led to the current state. Akka stores these events in a journal. Event Sourced Entities persist their state with ACID semantics, scale horizontally, and isolate failures. Views Views allow you to access multiple entities or retrieve entities by attributes other than their entity id. You can create Views for different access patterns, optimized by specific queries, or combine multiple queries into a single View. Key Value Entities Key Value Entities are entities that persist the full state on every change. HTTP Endpoints An Endpoint is a component that creates an externally accessible API. Endpoints are how you expose your services to the outside world. Workflows Workflows implement long-running, multi-step business processes while allowing developers to focus exclusively on domain and business logic. Workflows provide durability, consistency and the ability to call other components and services. Business transactions can be modeled in one central place, and the Workflow will keep them running smoothly, or roll back if something goes wrong. Timers Timers enable the scheduling of calls for future execution, making them particularly useful for verifying the completion status of processes at a later time. Consumers Consuming and producing allow stream based interaction between services and also with the outside world.
