Oct 1, 2025October 2025: Strengthened Vald's CI/CD pipeline with a focus on cross-architecture support, pipeline reliability, and consistent tagging. Delivered multi-arch Docker image builds (amd64/arm64) via GitHub-hosted runners, with an improved build matrix for main branches, tagged releases, and PRs. Prepared the workflow for multi-workflow Docker builds to enhance reliability and efficiency. Implemented key fixes to Docker build permissions in GitHub Actions and narrowed the Go build scope in related workflows to reduce failures. Refined Docker tagging and manifest workflows to ensure all extra_tags are correctly applied across the pipeline. These changes reduce release friction, broaden deployment options, and set a foundation for scalable, maintainable CI/CD.

Sep 1, 2025In Sep 2025, delivered gRPC configuration tuning for Vald to improve performance and resource utilization by updating default gRPC parameters across configuration files (idle_timeout, shared_write_buffer, enable_channelz, enable_admin). The change was implemented as a focused, low-risk configuration update with a single commit, aligning with performance optimization and operational efficiency goals. No major bugs fixed this month; the work focused on delivering measurable configuration improvements and preparing Vald for scalable operation.

Apr 1, 2025April 2025 (vdaas/vald): Delivered stability, concurrency, and data-structuring capabilities with clear business value. Build System Stabilization and CodeQL Action Versioning reduced CI flakiness and ensured timely security/quality checks by fetching the latest CodeQL actions and stabilizing generated-file handling. Streaming APIs with a concurrency parameter enable safe, scalable gRPC operations. Bidirectional Key-Value Store Library introduces a new data structure with forward/inverse iteration, backed by unit and integration tests for thread-safety. Overall impact: more reliable development workflows, faster feedback on quality gates, and enhanced runtime capabilities for concurrent workloads.
