From 271faf0f00991f8d83d515c2795f5cb11eae4f18 Mon Sep 17 00:00:00 2001 From: Kelly Date: Sat, 13 Dec 2025 01:09:02 -0700 Subject: [PATCH] perf: Optimize dashboard queries for faster load times MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Use pg_stat for approximate product count (instant vs full scan) - LIMIT on DISTINCT queries for brand/category counts - Single combined query (reduces round trips) - Add index on store_product_snapshots.captured_at - Add index on worker_tasks.worker_id and created_at 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 --- .../097_worker_tasks_worker_id_index.sql | 11 +++ backend/src/routes/markets.ts | 70 +++++-------------- cannaiq/dist/index.html | 6 +- 3 files changed, 33 insertions(+), 54 deletions(-) create mode 100644 backend/migrations/097_worker_tasks_worker_id_index.sql diff --git a/backend/migrations/097_worker_tasks_worker_id_index.sql b/backend/migrations/097_worker_tasks_worker_id_index.sql new file mode 100644 index 00000000..e3bc1953 --- /dev/null +++ b/backend/migrations/097_worker_tasks_worker_id_index.sql @@ -0,0 +1,11 @@ +-- Migration: Add indexes for dashboard performance +-- Speeds up the tasks listing query with ORDER BY and JOIN + +-- Index for JOIN with worker_registry +CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_worker_tasks_worker_id +ON worker_tasks(worker_id) +WHERE worker_id IS NOT NULL;
