Geo Searches for Healthcare Pricing Data

Robert Stewart, Castlight Health

May 10 2013


This talk covers the MongoDB deployment architecture used at Castlight Health to support very low latency spatial searches against our database of hundreds of millions of healthcare prices. The Geo haystack index in MongoDB and SSDs turned out to be the perfect solution for our problem. A strategy of replica set flipping also enables Castlight to swap in very large changes to the pricing data with no impact to the running application.
