Abstract: An embodiment includes determining, based on historical data associated with a specific task, a baseline bandwidth recommendation for completing the specific task. The embodiment assigns, for a first time period, the specific task to a first computing device on a network. The embodiment allocates, for the first time period based on the baseline bandwidth recommendation, a first baseline bandwidth to the first computing device. The embodiment allocates, for the first time period, a portion of a shared buffer bandwidth as a first buffer bandwidth to the first computing device based on a weight value assigned to the specific task. The first buffer bandwidth combines with the first baseline bandwidth as a first total bandwidth for the specific task. The embodiment throttles, during the first time period, data packets associated with the specific task based on the first total bandwidth for the specific task.

Abstract: A lightweight database-management system (DBMS) is based on a dynamic microservices architecture that implements each granular DBMS feature or function as a distinct, independently executable microservice. The DBMS's Parser front-end responds to each incoming query by selecting the first bind-time database feature needed to process the query. The Parser forwards its selection through a Channel-Binding subsystem to an Event Services Activation subsystem that activates a corresponding microservice to perform the selected feature. The first feature then selects the next required bind-time feature for activation, and this process continues sequentially until all required bind-time microservices have been identified, activated, and run. Runtime query-processing features are then sequentially selected in a similar manner. However, each selected runtime microservice is preloaded but not run.
