基于流数据的动态存储技术

对比了传统的数据与流数据的存储方法，并总结了现有流数据存储方式的优缺点，在继承了双向流的优点基础上，针对多数据源、多查询及多级存储建立了一个新的流数据处理系统模型，给出了解决历史数据存储的几种方案，更加突出了“实时性与历史性结合”的特点，同时满足了历史数据查询的需要，实现了流数据的动态存储策略。

Dynamic store technology base on streaming data

Compared store method of traditional data with streaming data, advantage and disadvantage of streaming data is sum- marized, and advantage of bi-directional streaming data is inherited, and a new model of streaming data manage system base on multi-source data, multi-query and multi-store is founded. Several projects to resolve historicaldata is put forward. The combinative characteristic of historical data andreal-time data is stand out. Query need of historical data is satisfied. Dynamic store technology of streaming data is realized.
