TiCDC OpenAPI v2

TiCDC provides the OpenAPI feature for querying and operating the TiCDC cluster. The OpenAPI feature is a subset of the cdc cli tool.

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

The request body and returned values of all APIs are in JSON format. A successful request returns a 200 OK message. The following sections describe the specific usage of the APIs.

In the following examples, the listening IP address of the TiCDC server is 127.0.0.1 and the port is 8300. You can specify the IP address and port bound to TiCDC via --addr=ip:port when starting the TiCDC server.

API error message template

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

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

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

Return format of the API List interface

If an API request returns a list of resources (for example, a list of all Captures), the TiCDC return format is as follows:

{ "total": 2, "items": [ { "id": "d2912e63-3349-447c-90ba-wwww", "is_owner": true, "address": "127.0.0.1:8300" }, { "id": "d2912e63-3349-447c-90ba-xxxx", "is_owner": false, "address": "127.0.0.1:8302" } ] }

In the above example:

  • total: indicates the total number of resources.
  • items: an array that contains all the resources returned by this request. All elements of the array are of the same resource.

Get the status information of a TiCDC node

This API is a synchronous interface. If the request is successful, the status information of the corresponding node is returned.

Request URI

GET /api/v2/status

Example

The following request gets the status information of the TiCDC node whose IP address is 127.0.0.1 and port number is 8300.

curl -X GET http://127.0.0.1:8300/api/v2/status
{ "version": "v7.3.0", "git_hash": "10413bded1bdb2850aa6d7b94eb375102e9c44dc", "id": "d2912e63-3349-447c-90ba-72a4e04b5e9e", "pid": 1447, "is_owner": true, "liveness": 0 }

The parameters of the above output are described as follows:

  • version: the current version number of TiCDC.
  • git_hash: the Git hash value.
  • id: the capture ID of the node.
  • pid: the capture process ID (PID) of the node.
  • is_owner: indicates whether the node is an owner.
  • liveness: whether this node is live. 0 means normal. 1 means that the node is in the graceful shutdown state.

Check the health status of a TiCDC cluster

This API is a synchronous interface. If the cluster is healthy, 200 OK is returned.

Request URI

GET /api/v2/health

Example

curl -X GET http://127.0.0.1:8300/api/v2/health

If the cluster is healthy, the response is 200 OK and an empty JSON object:

{}

If the cluster is not healthy, the response is a JSON object containing the error message.

Create a replication task

This interface is used to submit a replication task to TiCDC. If the request is successful, 200 OK is returned. The returned result only means that the server agrees to run the command but does not guarantee that the command will be run successfully.

Request URI

POST /api/v2/changefeeds
