Joiner transformation
Joiner transformation is used to join two heterogeneous sources. You can join data from same the source type also. The minimum criteria for joining the data are a matching column in both the sources. A mapping indicating the Joiner transformation is shown in the following screenshot:
Joiner transformation has two pipelines, one is called Master and the other is called Detail. We do not have any left or right Join as we have in SQL database.
To use Joiner transformation, drag all the required columns from the two sources into Joiner transformation, and define the Join condition and Join type in the properties.
