dax_ppdb is a package in the LSST Science Pipelines.

This package provides a Python interface for the Prompt Products Database (PPDB). Its initial version was developed primarily for performance testing of various implementation options as a part of the lsst-dm/l1dbproto package. Several modules/classes were moved to this package and renamed. It is expected that this implementation will further evolve to support features necessary for the Alert Production Pipeline.
