Window function是OLAP的查询中比较常见的SQL construct,提供了“引用临近区域元组”的语义,这种语义使得一些分析型query的编写更加简单,可以避免不必要的相关子查询结构。此外,很多系统(Oracle/PolarDB) 内部也实现了用window function做subquery unnesting,避免相关子查询的低效执行,因此window算子本身的高效实现意义就更大...
其中CMS是Crystal的核心,其包含2个cache,较小的requested region(RR) cache和较大的oracle region(OR) cache,分别用来响应近期的查询请求和长期的负载趋势。 与DBMS的整体交互流程是 DBMS通过connector向crystal发送数据请求(query),包括remote file path + 下推谓词 CMS与Matcher交互,判断在RR/OR中的cached region是...
in-memory databases provide faster query processing and anear-real-timeresponse. Storing data in memory offers several potential benefits over traditional databases, including lessI/Ooverhead and the ability to handle larger databases. Examples of in-memory databases includeSAP S/4HANA, Oracle TimesTen...
Fast Query Performance: They allow quick analysis of large datasets. Simply put, OLAP cubes take our tables, which are flat and two-dimensional (think like spreadsheets), and elevate them into something that has three (or many more) dimensions. OLAP cubes add additional layers and associations....
Consequently, this results in improved query performance and more precise insights. Why MySQL HeatWave? Intelectivo began evaluating AWS, Azure, and Google as possible providers for its Plugger BI solutions. The company wanted a platform that supported the MySQL datab...
