SOLR / SOLR CLOUD

6:00 pm - Meet & Greet

6:30pm - Presentation by Rishi Easwaran

Rishi Easwaran is a Principal Software Engineer at Aol. With over a decade of experience in technology. During his 7 years at Aol, he has successfully worked on numerous challenging large scale projects, with tight deadlines. The teams most recent accomplishment was re-architecture of Aol Mail’s Search infrastructure to a Hybrid Cloud deployment. Over the years, the entire team focused on performance, availability and scalability of SOLR.

Summary: Our goal is to provide a high availability search as a seamless service to multiple clients. On an average our system handles more than a billion transactions per day with indexes varying in size from 1MB to 100 GB. Such size and load variation poses us a unique set of performance, availability and scalability problems to overcome, still we manage to average 10 ms update and 50 ms search times. Items that I plan to discuss during this talk are:

• Architecture of our tiered search infrastructure supporting over 400 TB of index and its cost savings

• Deployment strategy

• Cluster management
