    • Rows to Generate

      A maximum of 1,000,000 rows of data can be generated.

    • Conflict Policy

      If you select Skip, the system skips data rows in conflict and continues generating data. If you select Replace, the system replaces existing rows with new ones that have the same primary key.

    • Generation Mode

      On the Create Task page, double-click one column you want to select. Set rules for generating data randomly based on the column information. For example, if the column name is time, you need to specify start and end time and the generation format. Alternatively, select Based on current time.

  9. Click Preview to check whether the data that will be generated can meet your requirements. If not, adjust the generation rules.
