Problem:

Candidate selectors are using the full PID tables with a fine n_sigma granularity which is not needed.
Using the lite PID tables with reduced granularity might reduce the memory consumption of jobs including the selectors.

Solution:

It would probably also help to split the hadron PID tables (p K pi) and the lepton PID tables (e mu).

Hi @vkucera ! Sorry, I missed this comment. Do you mean the following:

using BigTracksHadronPID = soa::Join<BigTracks,
                                  aod::pidTPCPi, aod::pidTPCKa, aod::pidTPCPr,
                                  aod::pidTOFPi, aod::pidTOFKa, aod::pidTOFPr>;
using BigTracksLeptonPID = soa::Join<BigTracks,
                                  aod::pidTPCEl, aod::pidTPCMu,
                                  aod::pidTOFEl, aod::pidTOFMu>;
