File: spring-kafka-example/README.md:12-17
Timestamp: 2025-07-22T01:35:41.406Z
Learning: User igorcampos-dev prefers minimal, high-level documentation in README files without detailed version specifications, choosing to keep tech stack information simple rather than adding precise version numbers.

Repo: igorcampos-dev/spring-integrations-examples PR: 21
File: spring-kafka-example/compose.yaml:30-32
Timestamp: 2025-07-22T01:30:57.054Z
Learning: User igorcampos-dev prefers to maintain environment parity between local development and production, avoiding development-specific configurations like ALLOW_PLAINTEXT_LISTENER even when they might provide clearer intent or safety nets.

File: spring-kafka-example/compose.yaml:3-4
Timestamp: 2025-07-24T01:40:49.337Z
Learning: User igorcampos-dev requires hard-coded container names in Docker Compose files (like `container_name: app`) for CI pipeline validation purposes, which is a valid operational requirement that overrides the general best practice of avoiding hard-coded container names.

Timestamp: 2025-07-27T19:57:31.204Z
Learning: In the spring-integrations-examples project, user igorcampos-dev prefers to keep simple example implementations minimal without additional error handling complexity, as the examples are for demonstration purposes rather than production use.
