JSON (JavaScript Object Notation) is a commonly used semi-structured data type. With the self-describing schema structure, JSON can hold all data types, including multi-level nested data types, such as Array, Object, etc. JSON takes advantage of high flexibility and easy dynamic expansion compared with the structured data types that must strictly follow the fields in a tabular data structure.

As data volume increases rapidly in recent years, many platforms have started to use and get the most out of semi-structured data types (such as JSON). For example, the JSON data is shared by various platforms through open interfaces, and the public datasets and application logs are stored in JSON format.

About RFCs

The importance of RFCs has been emphasized by many people. As @tison said in How to Participate in the Apache project community:

A description is certainly needed for any non-trivial change to explain the motivation. For major changes, design documentation becomes even more necessary since no one has a permanent memory, and people always forget why they did something in the first place. The precipitation of design documentation plays a vital role in freeing the community from the uncertain evolution of human activities.

Databend, developed with Rust, is a new, open-source data warehouse with a cloud-oriented architecture. It is committed to providing fast elastic expansion capabilities and a pay-as-you-go user experience. GitHub：https://github.com/datafuselabs/databend

Introduction

This article introduces the Databend base: Fuse Engine, a powerful columnar storage engine. The engine was designed by the Databend community with the following principles: Powerful performance, simple architecture, and high reliability.
