// caused this Lambda function to be triggered const Bucket = event.Records[0].s3.bucket.name; const Key = decodeURIComponent(event.Records[0].s3.object.key.replace(/\+/g, ' ')); // Retrieve the object s3.getObject({ Bucket, Key }, function(err, data) { if (err) { console.log...
Additional Lambda layer containing theAWS.Tools.Common,AWS.Tools.S3, andAWS.Tools.EventBridgemodules fromAWS Tools for PowerShell. The layer ARN is stored in Parameter Store. S3 bucket to store CSV files. Lambda function triggered by S3 upload. Custom EventBridge event bus and rule to send ...
Serverless Framework-based AWS Lambda function triggered by S3 events to resize images with the excellent Sharp module. By using the Sharp module (which uses the libvips library), image processing can be 3x-5x faster than using ImageMagick, thus reducing the time your function spends running, whi...
Image processing:Lambda functions can be triggered to process images as they are uploaded to S3. Data analytics:Lambda functions can be triggered to analyze data streams from Kinesis or DynamoDB. Real-time notifications:Lambda functions can be triggered to send notifications to users when certain ev...
Concurrency. By default, the concurrent execution for all AWS Lambda functions within a single AWS account are limited to 1,000. (You can request a limit increase for this number by contacting AWS support.) Any Lambda executions triggered above your concurrency limit will be throttled and will ...
而后上传至s3://test-bucket-dev桶,bthlt目录下. test.csv is generated locally and uploaded to ...
For example, if your Lambda function is triggered by - incoming S3 events, use the AWSSDK.Lambda.S3Events package incoming Kinesis events, use the AWSSDK.Lambda.KinesisEvents package incoming SNS notifications, use the AWSSDK.Lambda.SNSEvents package incoming SQS messages, use the AWSSDK.Lambda...
Make the function environment-agnostic, and use the source event to control execution. For example, when a Lambda is triggered from a S3 file upload, save the result back to the same S3 bucket. Keep the configuration inAPI Gateway Stage Variables, if you use API Gateway ...
If a Lambda function is not logging to CloudWatch, first ensure that the function is being invoked by the caller. Check the logs of the calling service and any CloudWatch metrics that indicate an event has triggered the function. Next, check the CloudWatch Logs for the function. All Lambda ...
Event-driven Architecture: Lambda functions can be triggered by various AWS services, such as S3, DynamoDB, and API Gateway, or custom events. This event-driven architecture empowers developers to create responsive applications that automatically react to data changes or external events. It...
