Configure Sampling and Finish Discovered Dependencies - trillium_discovery - Latest

When you discover dependencies, the analysis is run against a sample of your full data set. The final steps to discovering a dependency are to configure the sample options then run the analysis.

To configure sampling and finish discovered dependency analysis

1. In the Discover Dependencies window, click the Finish tab.
2. To configure sampling options, keep the defaults or change them as follows:

   Sampling Option	Description
   Number of sample rows:	Enter the total number of rows you want analyzed. The default is the total number of rows in the data source. Note: If you have more than 10,000 rows, the default analysis process is performed on a maximum sample of 10,000 rows. It is not recommended to go beyond this value. Performance will decrease.
   Sample:	Select one of the following: Every row - Include all rows in the sample. Every nth - Enter a number to indicate how many rows to skip before selecting the next row to include. Random - Include a random sample of rows in the analysis. Enter a percentage of the total rows to sample. Note: The random % is the percentage chance of rows being included. Therefore, the actual rows loaded may be different for each load of the same file even if you specify the same percentage.
   Start sampling at row:	Enter the row position to begin the sample. The default is row 1.

3. Optional: Click Reset to Defaults to revert options back to the defaults.
