This pull request delivers major performance improvements to the admin dashboard and error group logs endpoints, as well as fixes a validation error in the detection category filter. The changes optimize database queries by using continuous aggregates, row estimate functions, and chunk pruning, resulting in significantly faster response times for endpoints that previously timed out on large datasets. The detection category filter is simplified, resolving a schema validation issue. Additionally, redundant queries are removed and validation schemas are aligned.

Performance Improvements

• Admin dashboard endpoints now use continuous aggregates and row estimate functions (approximate_row_count, pg_class.reltuples) for statistics, replacing expensive COUNT(*) scans and running queries in parallel. This reduces response times from over 30 seconds to under a second. (packages/backend/src/modules/admin/service.ts, [1] [2] [3] [4]
• Error group logs endpoint now applies logs.time bounds for TimescaleDB chunk pruning, removes expensive COUNT(*) queries, and eliminates redundant group fetches by reusing already loaded data. (packages/backend/src/modules/exceptions/service.ts, [1] [2] [3]; packages/backend/src/modules/exceptions/routes.ts, [4]

Validation and Schema Fixes

• Detection category filter on /api/v1/siem/detections is fixed by replacing the oneOf schema (string | array) with a simple type: array, allowing Fastify to auto-coerce single values to arrays. The Zod validation schema is updated to match. (packages/backend/src/modules/siem/routes.ts, [1] [2]

Documentation

• Changelog updated to document all notable changes, including performance improvements and validation fixes. (CHANGELOG.md, CHANGELOG.mdR8-R30)

Testing

• Tests for error group logs updated to reflect new logic and input parameters. (packages/backend/src/tests/modules/exceptions/service.test.ts, packages/backend/src/tests/modules/exceptions/service.test.tsL696-R704)

Frontend Cleanup

• Unused imports removed from the dashboard errors page for improved maintainability. (packages/frontend/src/routes/dashboard/errors/+page.svelte, packages/frontend/src/routes/dashboard/errors/+page.svelteL12-L30)
