MRS Kafka

Yes: The node task will be re-executed, and the following parameters must be configured: Maximum Retries Retry Interval (seconds)
No: The node task will not be re-executed. This is the default setting.

The MRS Kafka node is used to query the number of messages that are not consumed by a topic.

Table 1 and Table 2 describe the parameters of the MRS Kafka node.

**Table 1** Parameters of MRS Kafka nodes

Retry upon Failure	Yes	Indicates whether to re-execute a node task if its execution fails. Possible values: Yes: The node task will be re-executed, and the following parameters must be configured: Maximum Retries Retry Interval (seconds) No: The node task will not be re-executed. This is the default setting. NOTE: If Timeout Interval is configured for the node, the node will not be executed again after the execution times out. Instead, the node is set to the failure state.
Failure Policy	Yes	Operation that will be performed if the node task fails to be executed. Possible values: End the current job execution plan: stops running the current job. The job instance status is Failed. Go to the next node: ignores the execution failure of the current node. The job instance status is Failure ignored. Suspend current job execution plan: suspends running the current job. The job instance status is Waiting. Suspend execution plans of the subsequent nodes: stops running subsequent nodes.
