Data processing, a broad topic, intersects with the related concepts ofdata preprocessinganddata preparation. Both options commonly occur before an actual data processing activity, and both ensure proper data collection to enable the most effective data processing operations. This article is part of 6...
Parsing and translation. Optimization. Evaluation. 15.4 Sorting 排序结果集是非常常见的一个需求,排序本身也可以辅助一些其它运算,比如 Join 和 Duplicate Elimination。 除了读取完数据之后再进行排序外,也可以直接按照排序键的顺序来读取数据。比如在表上建立排序键的索引,然后通过索引来读数据。需要注意的是,索引只是...

and repopulates the mining structure. If you have models that are based on the structure, you can choose to update the models that are based on the structure, which means they are retrained on the new data, or you can leave the models as is. For more information, seeProcessing Data Mini...
Basic Concepts of Real-Time Data Processing 实时数据处理是指在数据生成的同时,能够对其进行捕获、处理和分析的过程。这种处理方式与传统的批处理(Batch Processing)相对立,后者通常需要在数据积累到一定量后才能进行处理。实时数据处理的核心在于其低延迟性和高效性,能够为决策提供及时的信息支持。
