JDBC Lookup Stage

Table of Contents

Example
Configuration

The JDBC Lookup query pipeline stage is used to call out to a database as part of a pipeline stage, to inject results into either the context/request or the pipeline document. For example, if you needed to look up a user from a DB and add their profile information onto a request for downstream use in a pipeline, the JDBC Lookup Stage would facilitate this.

You must first upload the JDBC driver to Fusion.

This stage supports asynchronous processing.
