Join processor
The Join processor concatenates the values of multiple fields into a single field with a delimiter between them.
To join fields:
- Select Create → Create processor.
- Select Join from the Processor menu.
- Set the Source Fields to the fields you want to join.
- Set the Delimiter to the separator placed between values.
- Set the Target field where the joined result is stored.
In YAML mode, configure the join processor using the following parameters. For the complete Streamlang syntax, refer to the Streamlang reference.
