Disadvantage of Using the Operational Affinity Algorithm for Load Balancing

The operational affinity algorithm for load balancing does not ensure an evenly distributed work load across data sources.

A hash value is allocated to a request according to the type of request and the properties of the request. A range of hash values represents an arbitrary group of unrelated requests. It is possible for one range of hash values to represent many more operations than another range of hash values. A given range of hash values might represent requests that are made frequently, another range of hash values might represents requests that are almost never made.
