Java Data Intensive Serving Container - JDisc

Vespa's Java container JDisc is optimized for a quick and easy dev-to-prod cycle, and for writing code which processes large amounts of incoming and outgoing data. It is fully integrated with the Cloud Config System, allowing for live reconfiguration without service interruption. The container exposes a servlet-like API for query processing that allows building RESTful web-services, and a storm-like API to do document processing. It exposes APIs for simple and performant federation across heterogeneous data sources.

The Vespa container is the home of all application specific code in Vespa. Vespa's request processing lifecycle is explained in further detail in the request processing overview.
