Ballerina's ballerina/observability module auto-instruments HTTP, database, and messaging calls with OpenTelemetry, cutting tracing boilerplate—but you still need to manage overhead and know when to add manual spans.
Avoid manual documentation drift by using Ballerina's built-in OpenAPI generator to emit machine-readable contracts directly from your service code during the build process.
Decide when to use Ballerina’s streaming API versus loading files into memory. Compare memory usage, complexity, and performance, then see sample code and how to validate each approach.
Decide when to use Ballerina's HTTP versus HTTPS listener. Compare setup, performance, and security trade-offs, then implement a keystore-backed HTTPS service with practical validation steps.
A diagnostic guide for Ballerina Swan Lake HTTP client timeouts and retry failures, covering ordered checks, configuration fixes, and escalation criteria.
Ballerina treats errors as typed return values, not invisible exceptions. See how union types and the check expression force you to handle failures at compile time—and what that costs you.
A technical guide on implementing JSON payload validation in Ballerina using record types and error-handling resources to return structured HTTP 400 responses.
Stop paying the 'boilerplate tax.' Learn how Ballerina's native 'service' keyword and network-aware types eliminate manual routing and DTO mapping in API development.
Deciding between typed records and map-based JSON handling in Ballerina services: a comparison of compile-time safety versus runtime flexibility, with working examples and validation steps.
