From e5de19af5c6df151b9011a1ed144cfd79d13e201 Mon Sep 17 00:00:00 2001 From: Stuart Corbishley Date: Mon, 1 Jun 2026 07:30:02 +0200 Subject: [PATCH 1/4] Defer dataclip search_vector indexing off the insert path (#4800) The dataclips AFTER INSERT trigger built search_vector with jsonb_to_tsvector on the synchronous insert path. For large bodies under load this could hold the connection past the timeout and roll back the insert, so the dataclip was never saved and the run's following events cascade-failed - losing the run. Move vector building off the insert path, mirroring the log_lines approach: - safe_jsonb_to_tsvector(regconfig, jsonb): COALESCE(body,'{}') so a NULL/wiped body yields ''::tsvector (never NULL, so it can't stick in the pending index), catching program_limit_exceeded -> ''::tsvector. - Partial index dataclips_pending_search_idx over (inserted_at) WHERE search_vector IS NULL, built CONCURRENTLY (dataclips is unpartitioned). - Drop the set_search_vector trigger and update_dataclip_search_vector function (down restores the program_limit_exceeded-catching version). - DataclipSearchVectorWorker on a dedicated dataclip_search_indexing queue (concurrency 1) drains pending rows newest-first with FOR UPDATE SKIP LOCKED, snowballing when its per-run budget is exhausted, otherwise minute-ly cron. Uses english_nostop to match the read side (Lightning.Invocation). Dataclip search is now eventually consistent. The insert no longer blocks on or rolls back from vector building. --- CHANGELOG.md | 7 + lib/lightning/config/bootstrap.ex | 9 +- .../dataclip_search_vector_worker.ex | 95 +++++++++ ...52_add_safe_jsonb_to_tsvector_function.exs | 24 +++ ...653_add_dataclips_pending_search_index.exs | 23 +++ ...54_drop_dataclip_search_vector_trigger.exs | 40 ++++ .../dataclip_search_vector_worker_test.exs | 186 ++++++++++++++++++ test/lightning/runs_test.exs | 37 ++++ 8 files changed, 419 insertions(+), 2 deletions(-) create mode 100644 lib/lightning/invocation/dataclip_search_vector_worker.ex create mode 100644 priv/repo/migrations/20260530184652_add_safe_jsonb_to_tsvector_function.exs create mode 100644 priv/repo/migrations/20260530184653_add_dataclips_pending_search_index.exs create mode 100644 priv/repo/migrations/20260530184654_drop_dataclip_search_vector_trigger.exs create mode 100644 test/lightning/invocation/dataclip_search_vector_worker_test.exs diff --git a/CHANGELOG.md b/CHANGELOG.md index 5b94dac21da..d84c0337200 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -32,6 +32,13 @@ and this project adheres to backfilled by a background worker rather than computed synchronously on every insert, so log search is eventually-consistent (typically within a minute).
