No. Kibi supports for External Data sources such as typically SQL and generic REST sources.

Kibi can query these sources on the fly at user navigation to create special filters or special “external query” aggregators (e.g. to use in visualizations).

Generally speaking, you have to load all the data that will intend perform search and complex analytics. But you do not need to materialize or import auxiliary data e.g. that is only used for visualizations or to create filters.
