Apache Calcite Review and Overview
Apache Calcite is a software that enables you to use a relational database for your needs. The software takes SQL Queries and gives you access to their source code from which you can customize it to your needs. Apache Calcite refrains from providing data processing algorithms, data storage and a metadata repository. Calcite mediates data between applications and data processing engines. Calcite doesn’t want to be responsible for any data since it can its job without additional complications.
The language used for a relational database
Apache Calcite provides sort of a user manual to navigate through the SQL language for creating your queries. There is also a relational algebra page that encapsulates all the information you might require to tailor your database and create relations within it. An API summary is available with proper detail about the methods available. All these details are made available to the user to optimize queries according to a cost model.
Data made easily available
A schema adapter is an application that allows a database management system to read data that is available as a table in a schema. The list of adapters is that calcite uses are mentioned on the website along with the engines that can be used. A driver is what will allow you to connect your application to Apache Calcite. JDBC driver is powered by Avatica which is an Apache product. It allows remote as well as local connections. This allows easy connection to third-party data sources.
Some fascinating features
Streaming data is the data that keeps slowing over a network and is not held for a longer time. Apache Calcite enables the management of streaming data. The software also provides materialized views and explains how to use several different types of it. A lattice is a framework that enables a materialized view and Calcite dives in the depth of it as well.
Calcite follows a holistic approach and aims to give the user an easy experience.
