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.
