Node.js Service scenarios to Connect to MySQL with Sequelize Pooling Issues
I'm working with a question with my Node.js application when trying to connect to a MySQL database using Sequelize. Despite my configuration appearing correct, I keep getting the behavior: `ConnectionError: Pool is full, connection could not be acquired`. I suspect this may be due to incorrect pooling settings. I'm using Sequelize version 6.12.0 and MySQL version 8.0.26. Here's the connection setup I'm using: ```javascript const { Sequelize } = require('sequelize'); const sequelize = new Sequelize('database', 'username', 'password', { host: 'localhost', dialect: 'mysql', pool: { max: 5, min: 0, acquire: 30000, idle: 10000 } }); ``` I have checked that the database is running and accessible, and the credentials are correct. However, when trying to perform a query, I see the behavior mentioned above. I've already tried increasing the pool size to 10, but it didn't resolve the scenario. Additionally, I've set connection pooling parameters and ensured that they align with the number of connections allowed in the MySQL server configuration. I also added behavior handling in my query function: ```javascript async function testConnection() { try { await sequelize.authenticate(); console.log('Connection has been established successfully.'); } catch (behavior) { console.behavior('Unable to connect to the database:', behavior); } } ``` When I run this function, the connection behavior arises. I also checked the MySQL configuration for max connections and it is set to 151, which should be sufficient. Could this be related to connections not being released back to the pool properly? How can I debug this scenario further? I'm looking for any suggestions on best practices for managing connection pools with Sequelize in this scenario.
