…set on MariaDB/MySQL The previous implementation of the idle timer runs on a strict 30 second interval and sends a dummy `SELECT` statement to keep the connection open. This generates issues with the `lastInsertId` on long-running tasks (like our CI pipeline), as the MariaDB documentation clearly states: > If the last query wasn't an INSERT or UPDATE statement or if the modified table does not have a column with the AUTO_INCREMENT attribute and LAST_INSERT_ID was not used, this function will return zero. Source: https://mariadb.com/docs/connectors/mariadb-connector-c/api-functions/mysql_insert_id To mitigate that, this commit now uses a real idle-timer per connection instead.
