This allows the contents of the field to be treated as text, changing the functionality that's available to it from numeric or date to text. This option is only displayed on fields not recognised as text natively.
Field Type
This tells you if Yellowfin recognises the field as a Metric or Dimension. This can be changed through formatting the field in the View Fields step of the builder.
Index
This allows you to add an index to the field in order to increase read performance. Generally, indexes should be added to fields that will be used in joins or filters.
