Abstract
This paper introduces a series of APIs and idioms in Java SE (Java Standard Edition), GreatFree, to program large-scale distributed systems from scratch without adopting any third party frameworks. When programming with GreatFree, developers are required to take care of rather than be invisible to most of the implementation issues in a distributed system. It not only strengthens developers’ skills to polish a system but also provides them with the techniques to create brand new and creative systems. However, taking care of many such issues is a heavy load because of the low-level of Java SE. To alleviate the burden to program with Java SE directly, GreatFree provides numerous APIs and idioms in Java SE to help programmers resolve indispensable distributed problems, such as communication programming, serialization, asynchronous and synchronous programming, resource management, load balancing, caching, eventing, requesting/responding, multicasting, and so forth. Additionally, as an open source tool to program, developers are able to strengthen their systems through not only adjusting GreatFree parameters but also upgrading GreatFree APIs and idioms themselves. According to the current intensive experiments, it is convenient for developers to program an ordinary or a large-scale distributed system from scratch with GreatFree.
Highlights
The paper exhibits an open-source programming tool, GreatFree, to assist developers to program large-scale distributed systems from scratch
Based on Java SE, GreatFree includes a series of APIs and idioms to ease the programming procedure
It contains a series of domain-specific APIs and idioms, which focus on the area of distributed systems, especially the large-scale ones whereas a generic programming language is required to deal with all of the issues in any domains
Summary
The paper exhibits an open-source programming tool, GreatFree, to assist developers to program large-scale distributed systems from scratch. For security reasons, some systems, such as a creative one in a new environment, are forced to implement from an initial level For those considerations, a bunch of APIs and idioms, which is named GreatFree, are proposed to assist developers to program distributed systems, specially the large-scale ones. GreatFree is different from the naked generic programming languages like Java SE First of all, it contains a series of domain-specific APIs and idioms, which focus on the area of distributed systems, especially the large-scale ones whereas a generic programming language is required to deal with all of the issues in any domains. The convenience of GreatFree is that developers’ programming loads are reduced magnificently for its well-defined APIs and idioms They need to be aware of the issues of distributed systems, they are not required to implement them using Java SE.
