Sailthru CTO, Ian White, to Present on the Evolution from Application-Level Sharding to Autosharding at MongoDB World 2014

June 24, 2014

Sailthru infrastructure solution, made possible via Mongo-Connector, resulted in zero downtime and improved performance as databases rapidly scale with ecommerce and media client growth

NEW YORK--(BUSINESS WIRE)-- Sailthru, the only customer interest-based automated personalization platform, will be at MongoDB World 2014 for CTO and co-founder Ian White to present on the company’s unique migration from application-level sharding to autosharding via Mongo-Connector, a tool created by MongoDB interns in 2013 to move data across sets.

Sailthru, a read-heavy and write-heavy software application has been a MongoDB customer since 2009. The company maintains 120 replica set nodes on metal infrastructure processing 40 TB, and 25,000 writes per second. Primarily working with ecommerce and media brands, Sailthru maintains over 850 million user profiles, 75 million products and URLs and delivers over 2 billion emails, SMS messages and push notifications each month.

“When we started working with MongoDB we were able to partition our data by client with application-level sharding but we were quickly handling too much data. Application sharding helped with our performance because there were smaller indexes due to collection partitioning, yet we ran into problems with uneven load distribution, limited single server capacity and the time-heavy need for manual rebalancing and allocation,” said Ian White, Chief Technology Officer and Co-Founder, Sailthru. “With MongoDB, they’re always a step ahead and since MongoDB 1.6 we’ve been able to leverage autosharding. Autosharding makes Sailthru more scalable than ever before -- we can select a shard key and a key collection and let it run. The trick was evolving from application sharding to autosharding with no downtime, which is where Mongo-Connector came in last summer. Mongo-Connector allowed us to pipe data into autosharded clusters with zero downtime. We can also use it to pipe data into alternate data stores such as Hadoop and Solr.”

Come hear Ian White present on the process of evolving Sailthru’s infrastructure from application-level sharding to autosharding at this year’s MongoDB World, the largest gathering of the global MongoDB database community. His presentation will dive into best practices for autosharding, how Sailthru’s database team found success with Mongo-Connector through additional improvements and what to look out for that can indicate your business needs to look at approaches to sharding more critically.
