The base class for all DataSources, especially custom DataSources. It must always be inherited. It provides a lot of core functionality to get configurations, ensure caching and more.
Important: in most cases you will inherit the CustomDataSource DataSource for custom data sources.
How to use with the VisualQuery
When using the VisualQuery you can just drag it into your query. This is what it usually looks like:
The above example shows two filters finding items and delivering them on the same stream.
Example Using ItemFilterDuplicates
A common scenario will also combine this using the ItemFilterDuplicates, in case various in-streams deliver the same item:
The StreamMerge DataSource has no settings to configure.
Note that it will automatically merge the streams in A-Z order of the In-Stream names.
