How to set query timeout in Sequelize?
In Sequelize, configuring query timeout is a crucial feature, especially when working with large databases or applications that require a seamless user experience. Below are the steps to set query timeout in Sequelize:Step 1: Update Sequelize ConfigurationFirst, ensure that the query timeout option is configured during Sequelize initialization. Sequelize leverages the connection settings of the underlying database library (e.g., PostgreSQL, MySQL) to set the timeout, which is typically defined in the Sequelize configuration file.For example, for PostgreSQL, you can use in the Sequelize configuration to specify timeout settings:Step 2: Set Timeout for Specific QueriesIf you need to set a timeout for specific queries rather than globally, Sequelize supports configuring it at the query level. You can achieve this by passing the parameter when invoking query methods:In this example, if the query execution exceeds 3 seconds, it will throw a timeout error.Step 3: Error HandlingAfter setting the timeout, it is essential to handle potential timeout errors correctly. Applications using timeout settings should always be prepared to catch and manage these errors appropriately:SummaryBy following these steps, you can effectively configure and manage query timeout in Sequelize, which is vital for maintaining database performance and user experience. Properly setting and handling query timeout ensures your application remains robust and user-friendly when encountering database query delays.
