In the example above, you can see that the current sample is a Random sample.
Initial Data: The sample is taken from the first set of rows in the first file or table that is part of the dataset.
In some cases, the Initial Data sample is the entire dataset.
Data from the rest of the first file or table or from other files or tables is not included in the data grid.
Tip: For purposes of loading the data, the initial data sample is generated and displayed at first. For a better representation of the entire dataset, you should create a new sample.
At the top of the panel, you can review the currently loaded sample. Each user has his own active sample on a dataset.
NOTE: When a new sample is generated, any Sort transformations that have been applied previously must be re-applied. Depending on the type of output, sort order may not be preserved.
Initial Data: By default, the application loads the first N rows of the dataset as the initial data sample when the Transformer page is opened. The number of rows depends on column count, data density, and other factors. If the dataset is small enough, the full dataset is used.
NOTE: By default, samples may be up to 10 MB in size. For datasets smaller than this limit, the entire dataset is loaded.
Click the link in the current sample card to see the list of all available samples.
Tip: To change the name of a sample, click its card in the list of all available. Then, click the Edit icon.
NOTE: Except for the initial data sample, all samples are generated based on the steps leading up to the location of the cursor in the recipe. If earlier steps are deleted or modified, the collected sample can be invalidated.
