Worked on the tkajtoch/kibana repository to enhance the Security Solution by delivering two core features focused on upgrade reliability and performance. Introduced performance testing and optimization for the /upgrade/_perform endpoint, using JavaScript and TypeScript to instrument CPU-intensive logic with APM and the withSyncSecuritySpan wrapper, addressing out-of-memory errors and timeouts under load. Developed bulk rule update capabilities with conflict resolution, updating the API to support scalable management of prebuilt rules and implementing user-facing modals for safer conflict handling. These improvements reduced manual intervention, improved data integrity during upgrades, and enabled faster, more reliable security rule updates across the platform.
Month: 2024-11 — Focused on performance optimization and reliability for the Security Solution in tkajtoch/kibana. Delivered two key capabilities that improve stability under load and accelerate safe upgrades of security rules. 1) Security Solution Upgrade Endpoint Performance Optimization - Introduced performance testing and optimization for the /upgrade/_perform endpoint. - Added withSyncSecuritySpan wrapper to measure synchronous functions in APM; target CPU-intensive logic; included performance testing results; addressed OOMs/timeouts; ensured reliable performance under stress. - Commit: bdb6ff128c8e9fbf83d5e38e9a771853a171fdd2 ([Security Solution] `/upgrade/_perform` performance testing (#197898)) 2) Bulk Rule Update and Conflict Resolution in Security Solution - Enhanced rule update functionality with bulk updates and conflict resolution for prebuilt rules. - Updated API to support bulk updates; default to MERGED version when customization is enabled; addressed issues with index and data view ID fields during upgrades. - Introduced modals and logic to manage conflicts so users can proceed with updates for non-conflicting rules. - Commit: 99160f52d6a2e0ad4698ca8e5ac40316ebb733c9 ([Security Solution] Rule Updates in bulk with conflicts (#196776)) Overall impact and accomplishments: - Improved upgrade reliability and performance for security rules, reducing runtime issues under load and ensuring safer upgrades. - Enabled scalable, bulk rule management with safer conflict handling, reducing manual intervention. Technologies/skills demonstrated: - Performance testing and APM instrumentation, withSyncSecuritySpan, CPU-intensive optimization - API design for bulk updates and conflict resolution, UX consideration with conflict modals - Secure upgrade workflows, reliability engineering, and data integrity during upgrades Business value: - Higher reliability for security rule upgrades, lower downtime risk, and faster, scalable upgrades for security features.
