In accordance with embodiments, there are provided mechanisms and methods for facilitating dynamic hierarchical management of queue resources in an on-demand services environment in a multi-tenant environment according to one embodiment. In one embodiment and by way of example, a method includes assigning, in runtime, by the database system, weights to at least one of a plurality of tenants and a plurality of message types. The assigned weights are capable of being dynamically scaled, in runtime, based on one or more factors. The method may further include allocating, in runtime, by the database system, resources to one or more of the plurality of tenants and one or more of the plurality of message types based on their assigned one or more weights of the weights. The allocated resources are capable of being dynamically modified, in runtime, based on scaling of the assigned weights.
