Lucene 4.0 is on its way to deliver a tremendous amount of new features and improvements. Beside
Real-Time Search & Flexible Indexing DocValues aka. Column Stride Fields is one of the “next
generation” features. DocValues enable Lucene to efficiently store and retrieve type-safe Document
& Value pairs in a column stride fashion either entirely memory resident random access or disk
resident iterator based without the need to un-invert fields. Its final goal is to provide a
independently update-able per document storage for scoring, sorting or even filtering. This talk will
introduce the current state of development, implementation details, its features and how DocValues
have been integrated into Lucene’s Codec API for full extendability.
