supported are all weaved by plugins. Developers can customize their own ShardingSphere just like building lego blocks. There are lots of SPI extensions for Apache ShardingSphere now and increase continuously ShardingSphere became an Apache Top Level Project on April 16, 2020. Welcome communicate with community via mail list. 1.1 Introduction 1.1.1 ShardingSphere-JDBC ShardingSphere‐JDBC defines itself to completely isolate each function, not only can stimulate the enthusiasm of the open source community, but also can guarantee the quality of the project. Apache ShardingSphere begin to focus on pluggable

Time Contributors Over Time Apache ShardingSphere is positioned as a Database Plus, and aims at building a new criterion and ecosystem above multi‐model databases. It focuses on how to reuse existing customize their ShardingSphere just like building with LEGO blocks. ShardingSphere became an Apache Top‐Level Project on April 16, 2020.

ElasticJob became an Apache ShardingSphere Sub project on May 28 2020. Welcome communicate with community via mail list. 1 1 Introduction Using ElasticJob can make developers no longer worry about the interface. Developers can introduce new job types through SPI, and they can easily give back to the community. 5.5.1 Job interface ElasticJob jobs can be divided into two types: Class-based Jobs and Type-based interfaces for cus‐ tomized implementation. ElasticJob community welcomes developers to feed back their implementations to the open‐source community, so that more users can benefit from it. 7.1 Job Sharding
