Apache S4是一个常规用途的、分布式的、可伸缩的、容错的、可插入式的平台用于处理联系的无限数据流。Apache S4填补了复杂的专有系统和面向批处理的开源计算平台之间的差距。我们的目标是开发高性能计算平台从应用编程的并行处理系统中固有的复杂性隐藏。
Apache S4 已经在 Yahoo 的系统中使用，用于处理每秒数以千计的搜索查询。
S4 is a general-purpose, distributed, scalable, fault-tolerant, pluggable platform that allows programmers to easily develop applications for processing continuous unbounded streams of data.
S4 motivation
S4 fills the gap between complex proprietary systems and batch-oriented open source computing platforms. We aim to develop a high performance computing platform that hides the complexity inherent in parallel processing system from the application programmer.
S4 implementation
The core platform is written in Java. The implementation is modular and pluggable, and S4 applications can be easily and dynamically combined for creating more sophisticated stream processing systems.
