| Ratio sampling | Enable this toggle if you want to specify the percentage of records you<br>want to extract from your input dataset to create your output subset of<br>data.<br><br>Information noteNote: This percentage is an approximate value.<br>For example, if the proportion is set to 20%, it might output 15% or 28%<br>of records. The higher the total number of records is, the more precise<br>the approximation will be. |
| Number of records | Enter the fixed number of records you want to extract from your input<br>dataset to create your output subset of data.<br><br>Information noteNote: If<br>you are designing a Streaming pipeline and you want to specify a fixed<br>number of records, you will need to add a Window<br>processor before this processor. |
