|       Name       |   Type   | Required | Default |                                                       Description                                                        |
|------------------|----------|----------|---------|--------------------------------------------------------------------------------------------------------------------------|
| data             | String   | Yes      | (none)  | Testing data, support json and protobuf format. If data is json format , it can be parsed multiple events by json array. |
| format           | String   | Yes      | (none)  | Data format.  The Optional values are `json`, `protobuf`.                                                                |
| [format].config  | Map      | No       | (none)  | Data format properties. Please refer to [Format Options](../formats) for details.                                        |
| interval.per.row | Duration | No       | 1s      | Interval time in seconds between each row. If it is 0, it will be generated as fast as possible.                         |
| repeat.count     | Integer  | No       | -1      | Repeat count. If it is -1, it will be generated infinitely.                                                              |
