Alert streams and Brokers

There is substantial activity ramping up in the alert area. Topics for review/discussion could include the LSST alert plan, the LSST broker plan, ZTF alerts (see session proposal by Eric Bellm), ANTARES plans for processing ZTF alerts, on-going alert experience in other projects, and developments from the recent workshop Building the Infrastructure for Time-Domain Alert Science in the LSST Era.
