In general, techniques for creating test-data fall in two broad areas, namely, test-data generation and test-data extraction, that differ significantly in their basic approach, run-time performance, and the types of data they create. Test-data generation relies on generation rules, grammars, and pre-defined domains to create data from scratch.
There two ways to create datasets: dynamically and by reading from a json file using sparksession. First, for primitive types in examples or demos, you can create datasets within a scala or python notebook or in your sample spark application. For example, here’s a way to create a dataset of 100 integers in a notebook.

By creating a dataset, you create a reference to the data source location, along with a copy of its metadata. Because the data remains in its existing location, you incur no extra storage cost, and don't risk the integrity of your data sources. Also datasets are lazily evaluated, which aids in workflow performance speeds.
