[GitHub] [beam] aaltay commented on pull request #15479: [BEAM-10937] Tour of Beam use reshuffle before reading files

   I think this example is correct but I do not know if it is necessary to introduce this complication. Reshuffle is useful to prevent fusion. Not all runners do fusion (for example direct runner does not) and I am not sure how much this example explains why reshuffle might be needed here.
