Overview
TAP (Table Access Protocol) is an IVOA service that provides access to general table data, including astronomical catalogs. On the Rubin Science Platform, it is provided by lsst-tap-service, which is derived from the CADC TAP service. The data itself, apart from schema queries, comes from qserv.
The tap
service consists of the TAP Java web service, a PostgreSQL database used to track user job submissions, and (on development deployments) a mock version of qserv.
Upgrading tap
normally only requires an Argo CD sync.
