What factors do you consider when choosing a connection-level or a host-level API in Akka HTTP for clients?
When choosing between connection-level and host-level APIs in Akka HTTP for clients, consider the following factors :
1. Connection Pooling : Host-level API provides built-in connection pooling, efficiently managing multiple connections to a single target endpoint. For high-throughput scenarios or when targeting multiple endpoints, use host-level API.
2. Request Routing : Connection-level API requires manual management of connections, making it suitable for simple use cases with direct control over request routing.
3. Connection Lifecycle : With connection-level API, you have more control over connection lifecycle, allowing precise handling of connection establishment, termination, and timeouts.
4. Load Balancing : Host-level API automatically handles load balancing across multiple connections, while connection-level API requires custom implementation for distributing requests.
5. Failure Handling : Host-level API offers better failure handling by retrying requests on different connections if one fails. Connection-level API needs explicit error handling strategies.
6. Complexity : Connection-level API is simpler and easier to understand but lacks advanced features provided by host-level API. Choose based on your application’s requirements and desired level of abstraction.
