Number Of Datastreams Per Object vs Ingest Time


  • 10,000 digital objects generated
  • each object gets an additional datastream, so that n=1 has 1 datastream and n=10,000 has 10,000 datastreams
  • datastreams are inline (CONTROL_GROUP="X"), active and versionable
  • datastreams do not have content except one (mandatory) element
The following xml snippet shows one generated datastream
<foxml:datastream CONTROL_GROUP="X" ID="escidoc.2" STATE="A" VERSIONABLE="true">
 <foxml:datastreamVersion ID="escidoc.2dsid" LABEL="my label" MIMETYPE="text/xml">

The ingest finished without problems, showing that it is possible to ingest objects with a number of inline d datastreams as high as 10000. Another observation is the increase in ingest time which seems to become superlinear over time. The images below show the outcome of the test run.
