DM-55320: Add a feature to prune unanchored quanta in qgraph building#367
Merged
Conversation
Expose the prune_unanchored_quanta parameter of QuantumGraphBuilder as
a CLI option. Accept a SOURCE:ANCHOR colon-separated pair of task
labels; source quanta with no reachable anchor quantum downstream are
removed along with their entire downstream chain.
This will replace lsst.ap.pipe.prune_orphan_preloads, a script that
patched the quantum graph after build to remove loadDiaCatalogs
quanta with no downstream associateApdb quantum as they have no
template coverage. Example:
pipetask qgraph ...
--prune-unanchored-quanta loadDiaCatalogs:associateApdb
