Google Cloud SQL advertises that it's only $0.0150 per hour for the smallest machine type, and I'm being charged for every hour, not just hours that I'm connected. Is this because I'm using a pool? How do I setup my backend so that it queries the cloud db only when needed so I don't get charged for every hour of the day?
const mysql = require('mysql');
const pool = mysql.createPool({
host : process.env.SQL_IP,
user : 'root',
password : process.env.SQL_PASS,
database : 'mydb',
ssl : {
[redacted]
}
});
function query(queryStatement, cB){
pool.getConnection(function(err, connection) {
// Use the connection
connection.query(queryStatement, function (error, results, fields) {
// And done with the connection.
connection.destroy();
// Callback
cB(error,results,fields);
});
});
}
