DataSync for Parquet is a single-direction (ServiceNow to file) integration that leverages bulk shares and allows for replicating table records from a ServiceNow instance to a local file. 


Prerequisites

(warning) You will need to install the Perspectium Core update set in your ServiceNow instance. You can request a download link for this update set by contacting Perspectium Support.

(warning) You will also need to have Hadoop installed. If you are using a Windows machine, follow this link. 


Procedure

To set up a DataSync for Parquet integration, follow these steps:

A shared queue should have been created by Perspectium Support upon initial configuration of your ServiceNow instance. 

Otherwise, follow Create a ServiceNow shared queue to create a queue that points to your Parquet.
