ClickPipes OpenAPI 参考文档

所有 ClickPipes 类型都可以通过 ClickHouse Cloud OpenAPI 以编程方式创建、更新和删除。本页介绍身份验证以及可用的 ClickPipes 端点，并为每种 ClickPipe 类型提供 curl 请求示例。

身份验证

ClickHouse Cloud API 使用 HTTP Basic 身份验证。你需要一个在目标服务上具有相应权限的 API 密钥 (key ID + key secret) 。有关如何创建 API 密钥，请参见管理 API 密钥。

在运行下面的任何示例之前，请先设置以下环境变量：

export KEY_ID=<your_key_id>
export KEY_SECRET=<your_key_secret>
export ORG_ID=<your_organization_id>
export SERVICE_ID=<your_service_id>

基准 URL

https://api.clickhouse.cloud/v1

端点

所有 ClickPipes 端点都限定在特定的 ClickHouse Cloud 服务范围内：

Method	Path	Description
`GET`	`/organizations/{organizationId}/services/{serviceId}/clickpipes`	列出所有 ClickPipes
`POST`	`/organizations/{organizationId}/services/{serviceId}/clickpipes`	创建 ClickPipe
`GET`	`/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}`	获取 ClickPipe
`PATCH`	`/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}`	更新 ClickPipe
`DELETE`	`/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}`	删除 ClickPipe
`GET`	`/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}/settings`	获取 ClickPipe 设置
`PUT`	`/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}/settings`	更新 ClickPipe 设置
`PATCH`	`/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}/scaling`	更新 ClickPipe 扩缩容
`PATCH`	`/organizations/{organizationId}/services/{serviceId}/clickpipes/{clickPipeId}/state`	更新 ClickPipe 状态 (启动/停止)

对于 CDC ClickPipes (Postgres、MySQL、MongoDB) ，还提供了用于共享 CDC 基础设施扩缩容的组织级端点：

Method	Path	Description
`GET`	`/organizations/{organizationId}/clickpipes/cdcScaling`	获取 CDC ClickPipes 扩缩容
`PATCH`	`/organizations/{organizationId}/clickpipes/cdcScaling`	更新 CDC ClickPipes 扩缩容

如需查看每个端点的完整请求和响应 schema，请参阅 API 参考文档。

示例

查看 ClickPipes 列表

curl -u "$KEY_ID:$KEY_SECRET" \
  "https://api.clickhouse.cloud/v1/organizations/$ORG_ID/services/$SERVICE_ID/clickpipes"

获取 ClickPipe

CLICKPIPE_ID=<your_clickpipe_id>
