Package com.netflix.spinnaker.front50.model

Class EventingS3ObjectKeyLoader

  • All Implemented Interfaces:
    com.netflix.spinnaker.front50.model.ObjectKeyLoader, java.lang.Runnable
    public class EventingS3ObjectKeyLoader
extends java.lang.Object
implements com.netflix.spinnaker.front50.model.ObjectKeyLoader, java.lang.Runnable
    An ObjectKeyLoader is responsible for returning a last modified timestamp for all objects of a particular type.

    This implementation listens to an S3 event stream and applies incremental updates whenever an event is received indicating that an object has been modified (add/update/delete).

    It is significantly faster than delegating to `s3StorageService.listObjectKeys()` with some slight latency attributed to the time taken for an event to be received and processed.

    Expected latency is less than 1s (Amazon
