A computer-implemented method is disclosed. The method comprises calculating a first new rank value in a rank address space for a first issue of a plurality of issues. The rank address space comprises unique, ordered values, and each of the plurality of issues has a rank value in the rank address space. The method further comprises determining whether a length of the first new rank value is greater than or equal to a first rebalancing trigger length. In addition, the method comprises, in response to determining that the length of the first new rank value is greater than or equal to the first rebalancing trigger length, identifying a first delay period that is to elapse before rebalancing the rank address space comprising updating at least one rank value of at least one of the plurality of issues to reduce a possibility of congestion in the rank address space. The method additionally comprises following the first delay period, rebalancing the rank address space.
