From c74cc4c67e0294e63de16b56cb30606fa9803987 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 29 Jan 2026 11:47:24 -0800 Subject: [PATCH 01/10] Optimize get_snippets filters to fix timeout issues The starredBy, labeledBy, and upvotedBy filters were causing statement timeouts (>30s) due to inefficient EXISTS subqueries being evaluated for every row in the snippets table (119k+ rows). Root cause: - EXISTS subqueries like `EXISTS (SELECT 1 FROM user_star_snippets WHERE snippet = s.id)` were evaluated for each of the 119k snippets - This is extremely slow because PostgreSQL scans the large snippets table first, then evaluates the EXISTS condition for each row Solution: - Changed from EXISTS subqueries to JOINs with pre-filtered CTEs - Pre-compute the filtered snippet IDs in CTEs (which operate on much smaller tables) - Then JOIN against these pre-filtered IDs instead of using EXISTS Performance improvements: - starredBy filter: timeout (>30s) -> <1s - labeledBy filter: timeout (>30s) -> <1s - upvotedBy filter: 6.7s -> <1s - politicalSpectrum filter: already uses index, no change needed Technical details: - Added filter detection flags: has_starred_filter, has_labeled_filter, has_upvoted_filter - Added pre-filtered CTEs: starred_snippet_ids, labeled_snippet_ids, upvoted_snippet_ids - Renamed upvoted filter variables to filter_upvoted_by_me/filter_upvoted_by_others to avoid column reference ambiguity with label_summary CTE Co-Authored-By: Claude Opus 4.5 --- .../database/sql/get_snippets_function.sql | 540 +++++++++--------- ...20260129_optimize_get_snippets_filters.sql | 364 ++++++++++++ 2 files changed, 625 insertions(+), 279 deletions(-) create mode 100644 supabase/migrations/20260129_optimize_get_snippets_filters.sql diff --git a/supabase/database/sql/get_snippets_function.sql b/supabase/database/sql/get_snippets_function.sql index b25eb41..7f22fe2 100644 --- a/supabase/database/sql/get_snippets_function.sql +++ b/supabase/database/sql/get_snippets_function.sql @@ -1,5 +1,16 @@ DROP FUNCTION IF EXISTS get_snippets; +-- Optimized get_snippets function +-- Key optimization: Uses JOINs with pre-filtered CTEs instead of EXISTS subqueries +-- for starred/labeled/upvotedBy filters.
