Data Factory supports wildcard file filters for Copy Activity
Friday, May 4, 2018
When you're copying data from file stores by using Azure Data Factory, you can now configure wildcard file filters to let Copy Activity pick up only files that have the defined naming pattern—for example, "*.csv" or "???20180504.json".
Wildcard file filters are supported for the following connectors. For more information, see the dataset settings in each connector article.
