Sending a Heartbeat

Send a heartbeat to avoid consumer group timeouts in the Streaming service. A consumer group is a set of instances that coordinate to consume messages from all partitions in a stream.

For more information about consumer groups, including the automatic rebalancing process, see Using Consumer Groups.

This task can't be performed using the Console.
Use the oci streaming stream group heartbeat command and required parameters to send a heartbeat:
```
oci streaming stream group heartbeat --stream-id <stream_OCID> --cursor <cursor> --endpoint <messages_endpoint>
```
Your first heartbeat request should use the value returned when you created a group cursor. Each subsequent request should use the value returned in the previous response.

For example:
```
oci streaming stream group heartbeat --stream-id ocid1.stream.oc1.phx.exampleuniqueID --cursor examplecursorvalue --endpoint https://cell-1.streaming.us-phoenix-1.oci.oraclecloud.com
{
  "data": {
    "value": "examplenextcursorvalue"
  }
}
```
For a complete list of parameters and values for CLI commands, see the CLI Command Reference.
Run the ConsumerHeartbeat operation to send a heartbeat.
