    Properties

    inputColumn?: string

    Name of the column holding the content the function is applied to.

    mergeKeyColumns?: string[]

    Columns that together identify a row across incremental runs, so results can be matched back to their source rows. When unset, the task derives an implicit key from Delta row tracking. If row tracking is also disabled there is no stable key, so each run reprocesses the entire source (a full refresh) rather than only the changed rows; set a key column or enable row tracking to keep runs incremental.

    tableName?: string

    Fully qualified three-part name of the source table (catalog.schema.table).
