Currently all Solr morphline use cases I’m aware of run in processes outside of the Solr JVM, e.g. in Flume, in MapReduce, in HBase Lily Indexer, etc. These ingestion processes generate Solr documents for Solr updates. Running in external processes is done to improve scalability, reliability, flexibility and reusability. Not everything needs to run inside of the Solr JVM.
We haven’t found a use case for it so far, but it would be easy to add an UpdateRequestProcessor that runs a morphline inside of the Solr JVM. Here is more background info: http://kitesdk.org/docs/current/kite-morphlines/index.html http://kitesdk.org/docs/current/kite-morphlines/morphlinesReferenceGuide.html http://files.meetup.com/5139282/SHUG10%20-%20Search%20On%20Hadoop.pdf Wolfgang.
