Author: Dany Marcoux Date: 2022-02-22 (Tue, 22 Feb 2022) Changed paths: M src/api/app/components/watchlist_component.rb Log Message: ----------- Check if object is a watched item with a single query As an example for a watched item with a watchable being a package. Before, we executed 2 queries. 1. Fetching all columns of the watched item: SELECT `watched_items`.* FROM `watched_items` WHERE `watched_items`.`user_id` = 1 AND `watched_items`.`watchable_type` = 'Package' AND `watched_items`.`watchable_id` = 3 LIMIT 1 2. Fetching the watchable (a package): SELECT `packages`.* FROM `packages` WHERE `packages`.`id` NOT IN (SELECT `packages`.`id` FROM `packages` WHERE `packages`.`project_id` = 0) AND `packages`.`id` = 3 Now, we execute 1 query: SELECT 1 AS one FROM `watched_items` WHERE `watched_items`.`user_id` = 1 AND `watched_items`.`watchable_type` = 'Package' AND `watched_items`.`watchable_id` = 3 LIMIT 1 While testing locally, it tends to be a bit faster by about 1ms. It's definitely more in production since the database has more workload, so executing more queries tends to be more expensive.
