Connection distribution within a connectional parallelism architecture

摘要

Example embodiments provide various techniques for distributing connections within a connectional parallelism architecture. In one embodiment, a method is provided where resource utilizations of connection groups are measured. Here, each connection group is assigned to one of multiple processors. A probability distribution is accessed that maps probabilities assigned to relative resource utilizations. A relative resource utilization of one of the connection groups is determined based on a resource utilization of the one connection group relative to other resource utilizations of other connection groups. A probability from the probability distribution is identified based on the determined relative resource utilization, and based on the identified probability, a connection is assigned to this connection group for execution by one of the processors assigned to this connection group.

1. A method of distributing connections within a connectional parallelism architecture, the method comprising:
accessing a record of previous connection group assignments for multiple connection groups; selecting one of the connection groups for a connection based on the record; determining a current relative resource utilization of the selected connection group as compared to other resource utilizations of other connection groups; identifying a probability from a probability distribution based on the determined current relative resource utilization; and based on the identified probability, assigning the connection to the selected connection group for execution by a processor assigned to the selected connection group; andwherein the probability from the probability distribution decreases as the determined current relative resource utilization increases.
