Background - Apache Calcite

2024年1月9日  Apache Calcite is a dynamic data management framework. It contains many of the pieces that comprise a typical databasemanagement system, but omits some key functions: storage of data,algorithms to process data, and a repository for storing metadata. Calcite intentionally stays out of the business of storing andprocessing data.
