Question

A team stores their application source as a versioned ZIP file in an S3 bucket, which serves as the source stage for an AWS CodePipeline pipeline. Developers report that after they upload a new artifact to S3, the pipeline sometimes takes several minutes to start, and occasionally does not detect the change at all. The team wants pipeline executions to begin reliably and near-instantly whenever a new object version is uploaded, using the recommended AWS approach. What should they configure?

Accepted Answer

Enable EventBridge notifications on the S3 bucket and configure a CloudTrail trail that logs S3 data events, then have the pipeline's S3 source action use the resulting EventBridge rule to trigger the pipeline.

Answer

Increase the CodePipeline source polling frequency by editing the pipeline's PollForSourceChanges setting to poll every 30 seconds.

Answer

Add a Lambda function invoked by an S3 event notification that calls the CodePipeline StartPipelineExecution API on each upload.

Answer

Enable S3 Transfer Acceleration on the source bucket so that artifact uploads and change detection complete faster.
