The Large Synoptic Survey Telescope (LSST) is a large, 8-meter, ground-based telescope that will survey half the sky every few nights in six optical bands. Starting in 2022, it will explore a wide range of astrophysical questions, ranging from discovering `killer' asteroids, to examining the nature of dark energy.

The LSST will generate up to 10 million real-time notifications to changes in the sky (either due to change of flux or motion), around a 10x increase over expected pre-LSST volumes. In this talk, I will overview the LSST data stream, talk about the current implementation plans for the processing system, and discuss challenges and opportunities in making high-volume data streams broadly useful by the astronomical community.
