My presentation focuses on how we implemented Solr 4 to be the cornerstone of our social marketing analytics platform. Our platform analyzes relationships, behaviors, and conversations between 30,000 brands and 100M social accounts every 15 minutes. Combined with our Hadoop cluster, we have achieved throughput rates greater than 8,000 documents per second. Our index currently contains more than 620M documents and is growing by 3 to 4 million documents per day. My presentation will include details about: 1) Designing a Solr Cloud cluster for scalability and high-availability using sharding and replication with Zookeeper, 2) Operations concerns like how to handle a failed node and monitoring, 3) How we deal with indexing big data from Pig/Hadoop as an example of using the CloudSolrServer in SolrJ and managing searchers for high indexing throughput, 4) Example uses of key features like real-time gets, atomic updates, custom hashing, and distributed facets. Attendees will come away from this presentation with a real-world use case that proves Solr 4 is scalable, stable, and is production ready.
