修改Kafka实例Topic分区的副本

功能介绍

修改Kafka实例Topic分区的副本。

调用方法

请参见如何调用API

URI

POST /v2/{project_id}/instances/{instance_id}/management/topics/{topic}/replicas-reassignment

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID,获取方式请参见获取项目ID

instance_id

String

实例ID。

topic

String

Topic名称。

请求参数

表2 请求Body参数

参数

是否必选

参数类型

描述

partitions

Array of partitions objects

期望调整的分区副本分配情况。

表3 partitions

参数

是否必选

参数类型

描述

partition

Integer

分区ID。

replicas

Array of integers

副本期望所在的broker ID。其中Array首位为leader副本,所有分区需要有同样数量的副本,副本数不能大于总broker的数量。

响应参数

请求示例

修改Topic分区的副本分布位置,分区1的副本分布在broker 1和broker 2,Leader副本在broker 1。

POST https://{endpoint}/v2/{project_id}/instances/{instance_id}/management/topics/{topic}/replicas-reassignment

{
  "partitions" : [ {
    "partition" : 1,
    "replicas" : [ 1, 2 ]
  }, {
    "partition" : 0,
    "replicas" : [ 0, 1 ]
  } ]
}

响应示例

SDK代码示例

SDK代码示例如下。

修改Topic分区的副本分布位置,分区1的副本分布在broker 1和broker 2,Leader副本在broker 1。
