In this talk, I introduce Alluxio, the fastest growing open source project in the big data ecosystem, and show how to leverage it for optimizing Solr performance. I'll begin with a brief introduction about how Alluxio works and why it's interesting for the Solr community. Next, I describe how to run Solr on Alluxio and cover basic integration scenarios. Lastly, I provide some performance comparisons between running Solr on Alluxio vs. a local FS and HDFS. Attendees will come away with a new toolset to help them use Solr to tackle a wide array of big data problems.
