Class BlobHandler

java.lang.Object
  org.apache.flume.sink.solr.morphline.BlobHandler

All Implemented Interfaces:

Configurable, HTTPSourceHandler

public class BlobHandler
extends Object
implements HTTPSourceHandler

BlobHandler for HTTPSource that returns event that contains the request parameters as well as the Binary Large Object (BLOB) uploaded with this request.

Note that this approach is not suitable for very large objects because it buffers up the entire BLOB.

Example client usage:

 curl --data-binary @sample-statuses-20120906-141433-medium.avro 'http://127.0.0.1:5140?resourceName=sample-statuses-20120906-141433-medium.avro' --header 'Content-Type:application/octet-stream' --verbose
