Description

Apache ShardingSphere

Apache ShardingSphere is positioned as a Database Plus, and aims at building a standard layer and ecosystem above heterogeneous databases. It focuses on how to reuse existing databases and their respective upper layer, rather than creating a new database. The goal is to minimize or eliminate the challenges caused by underlying databases fragmentation.

Background

There is a proposal about the background of ChaosEngineering as belows:

• Introduce ChaosEngineering for ShardingSphere · Issue #32 · apache/shardingsphere-on-cloud (github.com)

The ShardingSphereChaos controller is aiming at different chaos tests. 

Task

Propose a generic controller for ShardingSphereChaos, which reconcile CRD ShardingSphereChaos, prepare, execute and verify test.

• [ ] Support common ShardingSphere features, prepare test rules and dataset
• [ ] Generating chaos type according to the backend implementation
• [ ] Verify testing result with DistSQL or other tools

Relevant Skills

1. Master Go language, Ginkgo test framework
2. Have a deep understanding of Apache ShardingSphere concepts and practices.
3. Kubernetes operator pattern, kube-builder 

Targets files

ShardingSphereChaos Controller - https://github.com/apache/shardingsphere-on-cloud/shardingsphere-operator/pkg/controllers/chaos_controller.go, etc.
