Abstract: An order management tool, method, and system are disclosed. The order management tool can use clusters of two or more locations to generate fulfillment plans for orders. The order management tool can determine whether a cluster can fulfill an order and, if so, can determine, for each item of an order, a location within the cluster from which to send the item. The items may be consolidated at a sortation center. The locations can be stores and the clusters can cover a geographical area. The order management tool can also generate two fulfillment plans, one of which allocates the order within the cluster and one of which may use one or more locations outside of the cluster, and the order management tool can apply rules to compare the two fulfillment plans and select one of them.

Abstract: Techniques for partitioning a database are described. Consistent with some embodiments, a technique may include maintaining a plurality of database instances, the plurality of database instances having a first partition and a second partition. Additionally, the method may include assigning first invitations to the first partition and existing invitations to the second partition. The first invitations can be created after a first date. The existing invitations can be created before the first date and after a second date, and where the second date occurred before the first date. Furthermore, the method may include archiving old invitations, the old invitations being created before the second date. Subsequently, the method may include receiving an invitation request and requesting invitation information associated with the invitation request, the invitation request having at least one of an invitee identifier, an inviter identifier, and a unique identifier.
