MSPileup getPileupDocs has been refactored into WMCore.Services.MSPileup.MSPileupUtils.getPileupDocs. Other implementations (i.e. in Tools.Common, MSTransferor), should be replaced and deprecated.

@d-ylee , could you please elaborate more the reason for such Service and what exactly such service will do? Are you asking to have dedicate MicroService to fetch docs from MSPIleup MongoDB? or are you suggesting new end-point(s) within existing MSPileup service. Honestly, I do not understand the suggested idea.

@vkuznet Sorry, I think I missworded it. I meant that the function itself has been refactored under WMCore.Services.MSPileup.MSPileupUtils.getPileupDocs. The function is being used in multiple areas. Will update the description.

@d-ylee , thanks for clarification, now it make sense to me.
