Ask a question about TsFile #89

Open Andy1314Chen opened 7 years ago

Andy1314Chen commented 7 years ago

As an illustrative example, a single wind turbine can generate hundreds of data points every 20 ms for fault detection or prediction through a set of sophisticated operations against time series by data scientists, such as signal decomposition and filtration, segmentation for varied working conditions, pattern matching, frequency domain analysis etc..

tsfile中提供了如举例中的'signal decomposition and filtration, segmentation for varied working conditions, pattern matching, frequency domain analysis etc'的功能吗？ 在Get Started中只看到了write和read功能，这和一般的数据库有什么区别呢？

tsfile是一个时序数据的文件存储格式，与自定义的文件相比，开放的read接口中有时间、值、频率等过滤条件，便于读取。 segmentation for varied working conditions等功能是tsfile之上的IoTDB数据库项目的功能，目前还未开源，预计年底进行开源。
