In Spectrum, subflows are dataflows that can be reused within other dataflows. When working with Property Graph data in Spectrum, you can create subflows to query and retrieve feature IDs from Property Graph (for example, input PBKEY, retrieve BLDGID), or to fetch metadata associated with feature IDs from individual data tables. Data returned in this manner can be textual or spatial.
Subflows can also be used to expose metadata data tables from Buildings, Property Attributes, Parcel Boundaries, or World Points of Interest Premium.
The process of creating a subflow for use with Property Graph data begins with the Query DB stage, in which the database connection and the fields used as input parameters are defined.
Query results are returned as new fields in the dataflow. The information returned is based on field indexing.
Refer to the Spectrum Flow Designer Guide and the Spectrum Dataflow Designer's Guide for additional information about creating subflows.
