MongoDB have nice feature - update-in-place, that can improve performance on update operations.

This what should be done to achieve this:

  • Fix size of status field
  • Preallocate takenBy field
  • Preallocate takenAt field

This was more or less useless - because MongoDB quick understands, that paddingFactor should be increased to allow update-in-place, so only profit from this is keeping paddingFactor at 1 all the time.
