Jan Urbański

Jan Urbański is a PostgreSQL enthusiast and hacker.

His main areas of interest are PL/Python and the query optimiser.

Jan has been involved in writing some of the new features of the PL/PythonU procedural language, explored estimating query progress in runtime, contributes to the psycopg2 driver and maintains an asynchronous Postgres driver for Twisted called txpostgres.

Before that, he worked on alternative approaches to the genetic query optimiser (GEQO) for his Master's Thesis and text search selectivity estimation during Google Summer of Code. He's also gotten some code into GStreamer, an open source multimedia framework, and contributed a Twisted connector for the popular Python AMQP library, Pika.

He's currently Lead Engineer at New Relic, where he divides his attention between Apache Cassandra, PostgreSQL and writing distributed systems in Java.
