January 2026 performance snapshot for getsentry/sentry and getsentry/sentry-infra-tools. Focused on delivering measurable business value through routing cleanup, data-path robustness, and infrastructure hardening. Key work spans frontend migrations away from deprecatedRouteProps, EAP-driven issue detection improvements, API parameter modernization, and YAML-based infrastructure safeguards.

Month 2025-12 Performance Summary for getsentry/sentry: Key features delivered: - Occurrences on EAP enhancements: Implemented EAP read for group hourly count to support the is_escalating logic, added delete RPC retries with exponential backoff, renamed the EAP RPC class, and reorganized EAP attribute/definition files. Also prepared an outline for a staged rollout (S4S region first) to converge EAP counts with Snuba as the source of truth. - EAP integration for suspect data: Implemented EAP reads for error counts in suspect flag and suspect tag calculations, enabling closer data alignment between EAP and Snuba. Also added traces for trace-connected issues in related issues calculations. - Refactor and routing modernization: Migrated routing/layout to use Outlet for app body content rendering and admin layout; removed deprecatedRouteProps across auth layout, settings, relocation, and related views, improving maintainability and testability. - Improvements to reliability and test infra: Added retries for codeowners_auto_sync to reduce transient failures; migrated tests away from deprecatedRouterMocks across breadcrumbs, discover, router, and related modules to modern contexts. - Supporting quality and performance fixes: Snuba issue search fallback improved to truncate group_ids when too many candidates, avoiding empty results in edge cases; updated docs link for dynamic sampling samples in Discover. Major bugs fixed: - Codeowners reliability: Added retry attempts for code_owners_auto_sync to resolve race conditions with Commit/CommitFileChange creation (#104648). - Discover: Updated docs link for dynamic sampling samples (fixes broken link) (#104924). - Dynamic grouping: Removed unnecessary deprecatedRouteProps to reduce dead code and potential routing issues (#105003). - Snuba: Fall back to truncation for group IDs in issue search when filters are selective to prevent empty results (#105204). - Admin and routing cleanup: Removed deprecatedRouteProps/usages across multiple routes and migrated tests to modern patterns (Outlet) (#105xxx). Overall impact and accomplishments: - Increased reliability and data fidelity for EAP-powered analytics, enabling safer convergence with Snuba for suspect flags, error counts, and related issues. Reduced technical debt by modernizing routing and UI layout, improving developer velocity and testability. Strengthened resilience against rate limits and transient failures with targeted retry/backoff strategies. Established a foundation for broader EAP adoption and smoother UI changes with clearer ownership of data paths. Technologies/skills demonstrated: - Backend data pipelines: EAP integration with EndpointTraceItemTable RPC queries, count aggregation, and cross-source validation. - Frontend/server routing modernization: Refactor to Outlet-based routing, removal of deprecated props, and test infrastructure migration. - Reliability engineering: Retry/backoff strategies for RPCs and auto-sync tasks; resilience to rate-limiting. - Testing and documentation: Test migrations and documentation link updates to reflect evolving data sourcing and dynamic sampling docs.
