From 5057f29efc9972d9f10faea8a1522674998a9cb3 Mon Sep 17 00:00:00 2001 From: Copilot <198982749+Copilot@users.noreply.github.com> Date: Thu, 31 Jul 2025 13:31:53 +0200 Subject: [PATCH] Fix alert events ordering to show latest events first (#22309) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * Initial plan * Initial analysis: identify ordering issue in alert events Co-authored-by: harshach <38649+harshach@users.noreply.github.com> * Fix PostgreSQL query ordering in listAllEventsWithStatuses Co-authored-by: harshach <38649+harshach@users.noreply.github.com> * Add comprehensive test coverage and performance indexes for event ordering - Add CollectionDAOEventOrderingTest with 4 comprehensive test methods - Test chronological ordering, pagination, edge cases, and cross-database consistency - Add critical timestamp indexes for consumers_dlq and successful_sent_change_events tables - Indexes prevent table scans on ORDER BY timestamp DESC queries - Migration 1.9.1 includes both MySQL and PostgreSQL index definitions Addresses performance concerns and test coverage gaps identified in PR review. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude * Fix tests --------- Co-authored-by: copilot-swe-agent[bot] <198982749+Copilot@users.noreply.github.com> Co-authored-by: harshach <38649+harshach@users.noreply.github.com> Co-authored-by: Sriharsha Chintalapani Co-authored-by: claude[bot] <209825114+claude[bot]@users.noreply.github.com> Co-authored-by: Claude Co-authored-by: Sriharsha Chintalapani Co-authored-by: Teddy --- .../native/1.9.1/mysql/schemaChanges.sql | 14 ++ .../native/1.9.1/postgres/schemaChanges.sql | 14 ++ .../service/jdbi3/CollectionDAO.java | 2 +- .../jdbi3/CollectionDAOEventOrderingTest.java | 234 ++++++++++++++++++ .../main/resources/ui/src/rest/alertsAPI.ts | 2 +- 5 files changed, 264 insertions(+), 2 deletions(-) create mode 100644 bootstrap/sql/migrations/native/1.9.1/mysql/schemaChanges.sql create mode 100644 bootstrap/sql/migrations/native/1.9.1/postgres/schemaChanges.sql create mode 100644 openmetadata-service/src/test/java/org/openmetadata/service/jdbi3/CollectionDAOEventOrderingTest.java diff --git a/bootstrap/sql/migrations/native/1.9.1/mysql/schemaChanges.sql b/bootstrap/sql/migrations/native/1.9.1/mysql/schemaChanges.sql new file mode 100644 index 00000000000..7997832b7a3 --- /dev/null +++ b/bootstrap/sql/migrations/native/1.9.1/mysql/schemaChanges.sql @@ -0,0 +1,14 @@ +-- Add timestamp indexes for improved performance of event ordering queries +-- These indexes significantly improve performance of ORDER BY timestamp DESC queries +-- used in listAllEventsWithStatuses method for alert event retrieval + +-- Add descending timestamp index for consumers_dlq table +-- This table stores failed event subscription events +ALTER TABLE consumers_dlq ADD INDEX idx_consumers_dlq_timestamp_desc (timestamp DESC);
