[jira] [Updated] (GSOC-245) Apache ShardingSphere: Introduce new CRD as StorageNode for better usability
[ https://issues.apache.org/jira/browse/GSOC-245?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Liyao Miao updated GSOC-245:
----------------------------
Description:
h1. 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.
Page: [https://shardingsphere.apache.org/]
Github: [https://github.com/apache/shardingsphere]
h1. Background
There is a proposal about new CRD Cluster and ComputeNode as belows:
- #167
- #166
Currently we try to promote StorageNode as major CRD to represent a set of storage units for ShardingSphere.
h1. Task
The elementary task is that the storage node controller could manage the lifecycle of a set of storage units, like PostgreSQL, in kubernetes.
We don't hope to create another wheel like pg-operator. So consider using a predefined parameter group to generate the target CRD.
- [ ] Create a PostgreSQL cluster while a StorageNode with pg parameters is created
- [ ] Update the PostgreSQL cluster while updated StorageNode
- [ ] Delete the PostgreSQL cluster while deleted StorageNode. Notice this may need a deletion strategy.
- [ ] Reconciling StorageNode according to the status of PostgreSQL cluster.
- [ ] The status of StorageNode would be consumed by common storage units related DistSQLs
h1. Relevant Skills
1. Master Go language, Ginkgo test framework
2. Have a basic understanding of Apache ShardingSphere Concepts
3. Be familiar with Kubernetes Operator, kubebuilder framework
h1. Targets files
StorageNode Controller - [https://github.com/apache/shardingsphere-on-cloud/blob/main/shardingsphere-operator/pkg/controllers/storagenode_controller.go]
