Aggregating and serving local places data and ads at Citygrid

Ana Martinez (CityGrid Media), Kin Lane (API Evangelist)
Data Science, Ballroom CD

Join us for an in depth architectural review of the latest infrastructure built by Citygrid to process and serve the local places data available via Citygrid APIs.

We will present how Hadoop is used to process large amounts of inbound data from disparate sources and to solve the complex problem of matching for places.

We will also discuss how Hadoop is used to generate the Solr and MongoDB indexes used for serving.

We will describe the function of the places, content and ad APIs and SDKs, and the characteristics of their underlying data, in the context of real world use cases.

We will focus on some of the limitations of Lucene and Solr for geographic search, and discuss some of the most recent developments we are exploring for our next generation APIs.

Finally, we will give a preview of Citygrid’s next generation real time event processing system, inspired by Twitter’s Rainbird and build on top of Cassandra.
