Abstract

ElasticJob[1] is a distributed scheduling solution which is a suitable framework for Apache ShardingSphere[2] scaling data migration jobs.
This project is supported By Dangdang and builds with Java.
Elastic-Job is a lightweight, decentralized solution that provides distributed task sharding services.#

Proposal

The goal of this proposal is to bring the existing ElasticJob codebase, developers and community into the Apache Software Foundation (ASF) as ShardingSphere's sub-project.
This project started in Open Source on Github nearly 5 years.
ElasticJob is submitting this proposal to donate it to the Apache ShardingSphere Incubator under the Apache License, Version 2.0, in order to replace the existing scheduler framework.
These artifacts are currently available on GitHub at https://github.com/elasticjob/elastic-job-lite.#

Background

ShardingSphere is a excellent distributed database middleware and have many open source users at domestic and abroad.
But the current scheduler of data scaling can not support sharding and distribute job.
The project ElasticJob is another open source project which established by Apache ShardingSphere's VP Liang Zhang on 2014.
Just like data sharding with Apache ShardingSphere, ElasticJob focused on job sharding. The feature of current job scheduler of scaling is too simple and can not afford data migrate distribute job to . So Liang Zhang decide bring ElasticJob as a sub-project to provide distribute scheduler supporting.#

Current status

ElasticJob has no updated during previous 2 years because Liang Zhang do not have time to maintain the community. But it still has lots of users using ElasticJob in China. We think bring ElasticJob into Apache ShardingSphere community can help the project growth up. #

Core developer

Liang Zhang is an experienced open source developer and ShardingSphere VP.#
