Abstract:In the design of data_exchange ETL, the problem of Resource Scheduling influence the whole system's efficiency directly. So it is very important to write an efficient, easy-to-maintenance, and scalability system. There are resources to block in the case of frequent idle threads in many other scheduling systems. Always deployment of resources will increase a great deal of trouble to programmers. Because of software coupling, small changes will affect many parts of system. The small change will affect a lot of parts. This article uses the proxy pattern, the factory pattern to be applied to resource scheduling which reduced the coupling of software. We established a strong maintainability and scalability, the implementation of efficient scheduling system.
