Figure: Sample Bar

By default, the application loads the first N rows of the dataset as the sample, the number of which 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.

NOTE: When sampling from compressed data, the source is uncompressed, and a new sample of it is loaded into the data grid. As a result, the sample size you see in the grid corresponds to the uncompressed data.

  • To review details on the individual columns of your dataset, click Columns. See Column Browser Panel.
  • Click the Data Types link to review counts of the columns of each type. See Supported Data Types.

Tip: As you add steps to your recipe, these values are automatically updated. You can use these updates as one verification tool for your recipe steps.
