BEGINRELEASENOTES

  • Add a collsToRead argument to readEntry and readNextEntry for the ROOTFrameReader to allow limiting the collections that are actually read.

ENDRELEASENOTES

This is an (early) proposal for introducing this functionality which would in the end address #499

  • Interface design: Do we want to have the possibility to change this frame-by-frame?
    • Alternatively would have to introduce a configuration method that takes a category name and a list of collections.
  • Should we only pass on the limited collection id table?
    • Interplay with Frame and assumptions there
  • Same capabilities for RNTuple reader
  • Documentation (once the rest has settled)
