Astronomy has been transformed by the development of survey telescopes and software that allows scientists to analyze or interpret massive data streams. The DSA-2000 is a radio interferometer concept in development at Caltech that will extend this transformation to the radio domain. The DSA-2000 is unique among current and planned large radio telescopes, in that it will operate as a dedicated survey telescope. As radio signals are fully digitized, the DSA-2000 data is massively multiplexed, producing sensitive spectro-polarimetric images while simultaneously searching for pulsars and Fast Radio Bursts. The flagship survey of the telescope is a billion source radio catalog that can be matched to counterparts from the Rubin Observatory, SPHEREx, and SRG/eROSITA. The fusion of these massive data sets is a challenge faced by data centers worldwide and an opportunity to reveal the science at the intersection of astronomical domains.
