     # @note Internally in the rebalance manager we have a notion of lost partitions. Partitions
     #   that are lost, are those that got revoked but did not get re-assigned back. We do not
     #   expose this concept outside and we normalize to have them revoked, as it is irrelevant
     #   from the rest of the code perspective as only those that are lost are truly revoked.
