    JDBC Index Stage

    Table of Contents

    The JDBC Index Stage is used to connect to a database, lookup one or more values, and then inject them into the context. The properties for setting stage are identical to the JDBC Query Stage, except for the "rows" property, which defaults to -1 for the index stage (which returns all rows in the database), and defaults to 10 returned rows for the query stage.

    You must first upload the JDBC driver to Fusion.

    Example

    An example of a JDBC Index Stage setup

    Upload stage config via POST to Fusion REST API endpoint `api/index-stages/instances`
