Does anyone know any good RDF store based on Hadoop ?
This might be related in your context:
- not Hadoop, but HBase (to be concrete ;) ): "Storing RDF data into HBase?"
- "Best practices for processing RDF data using MapReduce (via Hadoop)?"
- "Native Triple Stores Performance"
I guess, that SHARD (HDFS based) is a hot potato.
I think @castagna may have made some progress since posting http://www.semanticoverflow.com/questions/716/storing-rdf-data-into-hbase
I'm curious why you are interested in HBase? I speculate that range queries in a map-reduce implementation isn't going to perform very well. I suspect other more mature stores that implement their own federation, such as Allegrograph and Virtuoso, may fair better if performance alone is your concern.
