MongoDB at eBay

At our next User Group we will have presentations from engineers at eBay who have been using MongoDB for over two years in production.

"Doubling Up on Shards"
John Feibusch – Sr MTS, Data Infrastructure
At eBay we had a situation where a shard cluster had not been expanded for some time and needed to grow quickly. Since it was about three terabytes per shard, normal chunk migration would have taken much too long. We found that we could split each shard into two by moving database files and altering cluster metadata. In this talk, we'll show you how we efficiently implemented this shard migration by pre-splitting shards.

"Indexing Metric Metadata with MongoDB"

Yuri Finkelstein – Principle MTS, Architect Platform Service

This presentation will cover the design of TopoStore a MongoDB based metadata store build by Sherlock team. Sherlock is a unified monitoring, alerting and logging platform for eBay that exposes real time data and insights, enabled by an extensible visualization platform.
