Although people usually come to Lucene and related solutions in order to make data searchable, they often realize that it can do much more for them. Indeed, its ability to handle high loads of complex queries makes Lucene a perfect fit for analytics applications and, for some use-cases, even a credible replacement for a primary data-store. It is important to understand the design decisions behind Lucene in order to better understand the problems it can solve and the problems it cannot solve.

During the session, “What is in a Lucene Index?,” Adrien Grand, Software Engineer at ElasticSearch, will explain the design decisions behind Lucene, and give insights into how Lucene stores data on disk and how it differs from traditional databases. Finally, there will be highlights of recent and future changes in Lucene index file formats.

This advanced level session will take place from 2:45-3:30 on Thursday, November 7. Click here for more details.
