A DataSource that merges all streams on the
In into one
The StreamMerge DataSource is part of the Standard EAV Data Sources. It will create a new stream containing everything which came into this data source.
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.
