Yes, it is possible to check whether transactions are supported by Aurora MySQL when accessed through a Node.js Lambda function.
One way to check is to execute a simple test query that uses a transaction and check for any errors. For example, you can use the following code to check if a transaction is supported:
const mysql = require('mysql2/promise');
exports.handler = async (event, context) => {
// create connection
const connection = await mysql.createConnection({
host: 'your-aurora-mysql-hostname',
user: 'your-username',
password: 'your-password',
database: 'your-database'
});
try {
// execute a transaction
await connection.beginTransaction();
await connection.query('INSERT INTO my_table VALUES (?)', ['Hello World']);
await connection.commit();
console.log('Transaction supported!');
} catch (err) {
console.log('Transaction not supported!', err);
} finally {
// close connection
await connection.end();
}
};
If transactions are supported, the code should output "Transaction supported!" in the CloudWatch logs. If not, it will output "Transaction not supported!" with an error message indicating why the transaction failed.
