Datasets identify the data used from a data source so that Kyvos can access and work with the data. You can register a dataset or a folder. Kyvos supports advanced datatypes like maps, arrays, and structs in HCatalog tables. You can fetch these with the help of a formula step in datasets using two formula functions to extract these data types. You can also apply some formatting and filters to the file when you register it. Formatting standardizes the appearance of data such as how dates are displayed. Filtering allows you to exclude data from the original source file that you don't plan to use.
If your instance of Kyvos is configured via the portal.properties file to support it; you can create a dataset with a Presto connection. However, you can't create a dataset or semantic model process using this dataset.
When you specify Lookup as you register the dataset, the complete data is processed for both full and incremental processes regardless of the data source type. See Using lookup to learn more.
You can set up properties to control how Kyvos handles data.
