Pipeline Function Error Handling

Each transform returns a true or false as part of the return signature. This is called the continuePipeline flag and indicates whether the SDK should continue calling successive transforms in the pipeline.

  • return false, nil will stop the pipeline and stop processing the event. This is useful, for example, when filtering on values and nothing matches the criteria you've filtered on.
  • return false, error, will stop the pipeline as well and the SDK will log the error you have returned.
  • return true, nil tells the SDK to continue, and will call the next function in the pipeline with your result.

The SDK will return control back to main when receiving a SIGTERM/SIGINT event to allow for custom clean up.
