Pipeline Function Error Handling
Each transform returns a
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, nilwill 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, niltells 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.
