Developed and delivered Spanner autoscaling samples for independent regional autoscaling of read-only replicas, contributing to both the renovate-bot/golang-samples and renovate-bot/java-spanner repositories. The work involved implementing asymmetric autoscaling logic in Go and Java, with each sample demonstrating how to configure autoscaling limits, targets, and replica selections for Google Cloud Spanner instances. Integration tests were added in both languages to validate the correct behavior of independent autoscaling across regions. This effort showcased skills in API integration, backend development, and cloud computing, providing practical, tested examples for developers working with Cloud Spanner’s autoscaling capabilities in real-world scenarios.
