Maintain DM Clusters Using OpenAPI

DM provides the OpenAPI feature for easily querying and operating the DM cluster, which is similar to the feature of dmctl tools.

To enable OpenAPI, perform one of the following operations:

  • If your DM cluster has been deployed directly using binary, add the following configuration to the DM-master configuration file.

    openapi = true
  • If your DM cluster has been deployed using TiUP, add the following configuration to the topology file:

    server_configs: master: openapi: true

You can use the APIs to perform the following maintenance operations on the DM cluster:

APIs for managing clusters

APIs for managing data sources

APIs for managing replication tasks

The following sections describe the specific usage of the APIs.

API error message template

After sending an API request, if an error occurs, the returned error message is in the following format:

{ "error_msg": "", "error_code": "" }

From the above JSON output, error_msg describes the error message and error_code is the corresponding error code.
