How can I use AWS SDK with Lambda for asynchronous operations?

You can use the AWS SDK in your Lambda function to call other AWS services asynchronously. This is done by using promises or async/await syntax.

Can you provide a code example for that?

Sure! Here's a simple example:

const AWS = require('aws-sdk');
const s3 = new AWS.S3();

exports.handler = async (event) => {
    const params = { Bucket: 'my-bucket', Key: 'my-key' };
    try {
        const data = await s3.getObject(params).promise();
        console.log('Data:', data);
    } catch (error) {
        console.error('Error:', error);
    }
};

What happens if the Lambda function times out?

If the Lambda function times out, any ongoing asynchronous operations will be terminated, and you may not receive the expected results. It's important to set appropriate timeout values.
