Fuse / Coalesce fields

Lets you combine multiple fields into one, selecting the first value that is non-null.

Use it to fuse data streams coming from different filter requirements. You can define new fields whose values represent whatever is available from one of the input streams.

Or use it to identify the most accurate or most recent observation, if multiple entries have been recorded in separate columns.
