⁠Vespa - The open big data serving engine

Store, search, organize and make machine-learned inferences over big data at serving time.

⁠Background

Use cases such as search, recommendation and personalization need to select a subset of data in a large corpus, evaluate machine-learned models over the selected data, organize and aggregate it and return it, typically in less than 100 milliseconds, all while the data corpus is continuously changing. This is hard to do, especially with large data sets that needs to be distributed over multiple nodes and evaluated in parallel.

Vespa⁠ is a platform which performs these operations for you with high availability and performance. It has been in development for many years and is used on a number of large internet services and apps which serve hundreds of thousands of queries from Vespa per second.

⁠Install

Run your own Vespa instance following our Getting Started Guide⁠.

⁠Usage

• The application created in the getting started guide is fully functional and production ready, but you may want to add more nodes⁠ for redundancy.
• See developing applications⁠ on adding your own Java components to your Vespa application.
• Vespa APIs⁠ is useful to understand how to interface with Vespa
• Explore the sample applications⁠
• Follow the Vespa Blog⁠ for feature updates / use cases
