Summary In Spring Boot microservices, developers often version APIs by copy-pasting controller classes, especially when the business logic change is minimal. This leads to significant code duplication, frequently caught by static analysis tools like SonarQube, which blocks the build due to quality gates. The specific scenario involves two controllers (v1 and v2) sharing nearly identical … Read more
Summary Ingesting 1TB per hour (approximately 278 MB/s) to Splunk Cloud using AWS Lambda alone is fundamentally constrained by Lambda’s concurrency model and network egress limits, leading to predictable throttling and data latency. The root cause is not a configuration error, but an architectural mismatch: attempting to use a stateless, burst-optimized compute service (Lambda) for … Read more
