Issue DM-2042: W16 Improve Data Provenance Design
We have a detailed design of the Provenance, described at https://dev.lsstcorp.org/trac/wiki/db/Provenance. Work covered by this epic involves: 1. Revisiting the design and tweaking it as necessary. In particular: * Describing in more details interactions with key data producers (DRP, AlertProd, Calibration, L3 data brought in by users). * Estimating the size of provenance data * Considering querying the provenance data 2. Evaluating existing off-the-shelf provenance systems/tools. Deliverable: a document describing data provenance architecture / schema supported by a standalone proof-of-concept prototype.
