Recap: Improving Hadoop Performance by (up to) 1000x | LinkedIn EngineeringDaniel Abadi recently visited LinkedIn and talked about "Improving Hadoop Performance by (up to) 1000x." Abadi is an assistant professor at Yale University and the Chief Scientist of Hadapt, a company he co-founded to commercialize the HadoopDB project. This post is a recap of Abadi's talk, which focused on how HadoopDB could combine the best of Hadoop and parallel databases to achieve dramatic performance improvements in data analytics tasks.

django-rdflib and postgresql - the best of both worlds — EuroPython 2011: Florence, June 20–26rdflib is a python library implementing a database with various triples back-end, parser, data serializers, SPARQL is a Python interface to extract/insert triples. We integrated it in Django reusing the database connection and exposing an ORM interface, along with full-text search on literals. This presentation shows a django-rdflib case study with a PostgreSQL backend in Brain Architecture Management System (http://brancusi1.usc.edu) - a neuroscientific project for the University of Southern California. Benefits of the flexible RDF structure will be shown, allowing researchers to insert free format data, making data public with a customizable serialization and use the powerful full-text search integrated in PostgreSQL.
