Description

it be nice to have more grouping info on cols available.
that helps with later structuring / aggregating in analysis
and should be easy to provide.

groups = char vecs of col names

potential groups

  • problem: id + all pars
  • algo: id + all pars
  • result / outcome: collected outcomes

i could come up with some more for the rest, but these are most useful. especially as these are dynamically defined by the user. the rest are known constants and created by bt all the time.

how could they be returned:

attributes of result. not the biggest fan of this. but might be ok here. could also provide some simple getters.

Research direction

Start with the reduceResultsDT and getJobTable entry points mentioned in the issue. Determine how dynamically defined user columns and batchtools' known constant columns are represented, then settle on a return interface for problem, algo, and result/outcome groups. Done means callers can retrieve these column groups for later structuring and aggregation.
