Abstract
In many computer systems, the rate of data from an input source may become significantly faster than a processor's ability to respond. This situation occurs when a faster and more modern system writes to an older and slower legacy system. The result of this interaction between disparate capacity systems may be system failure or data corruption, particularly due to overloading the slower system's input queue to the point where it can no longer catch up to its workload. The invention provides a method, system, and computer-readable medium having computer-executable instructions for transferring data between disparate capacity systems. The method comprises the steps of receiving transactions from a first computer system at a first rate and providing the transactions to a second computer system, wherein the second computer system receives the transactions at a second rate. The second computer system may be a database legacy database server and the first computer system may be an updated database server The second rate is set at a capacity of the second computer system. The method further delays for a predetermined period of time the transactions when the first rate exceeds the second rate. The predetermined period of time is a function of the second rate.
