The way you partition depends heavily on the nature of your data.In the following recipe, we will illustrate a methodology to utilize a data partitioning table for moving a large dataset. We will use a public Common Crawl dataset, which contains petabytes of web crawl data from 2008 to the present day. It is a public dataset hosted on the AWS S3 platform. We will only use a small subset of this data for our example, enough to illustrate the power of data factory parallel processing.
