# tRedshiftLookupInput

Reads a Redshift database and extracts fields based on a query.

It passes on the extracted data to tMap in order to provide the lookup data to the main flow. It must be directly connected to a tMap component and requires this tMap to use Reload at each row or Reload at each row (cache) for the lookup flow.
