Run Stitch

Stitch uses patented algorithms to evaluate massive volumes of data to discover the hidden connections in your customer records that identify unique individuals. Stitch outputs a unified collection of data that assigns a unique identifier to each unique individual that is discovered within your customer records.

Add tables to Stitch run

The Stitch process only runs against selected domain tables. A domain table is made available to Stitch from its feed settings (via the Make available to Stitch configuration setting). A domain table that is made available to Stitch must also be selected from the list of domain tables in the Stitch Settings dialog box.

The tables that are selected to be part of the Stitch run are processed and compared for identity resolution, which will result in assignment of Amperity IDs to each unique individual that is discovered across all of the domain table data included in the Stitch run.


Only tables with the Make available to Stitch setting enabled in the Feed Editor will be available in the Stitch Settings dialog box.

To add tables to the Stitch run

  1. From the Stitch tab, click Settings.

  2. In the Stitch Settings dialog box, under Table, select from the list of tables which ones are to be included in a Stitch run, and then click Save.

Run Stitch

A Stitch run can be started manually by clicking the Run button at the top of the Stitch tab. A Stitch run may be started automatically by an upstream process, such as after successful domain table updates that were initiated by courier group automation.


A Stitch run takes a certain amount of time, depending on the size of the data analyzed and the number of potential pairs in the data. In general, you should expect to wait at least 20 minutes (but as much as 2 hours) for the Stitch run to complete. You can navigate to other areas of Amperity and do other tasks while waiting for the notification to run and complete successfully. Stitch has two notifications: the Stitch run, and then the Stitch report. The UI will refresh with updates after the Stitch report.

To start the Stitch run manually

  1. From the Stitch tab, click Run.

Configure Stitch

A list of Stitch configuration settings is available from the Stitch tab. These settings should not be changed until after your first Stitch run and the Stitch QA process has started.

It is not uncommon to make some configuration changes after analyzing how Amperity has processed your data. Common configuration changes include adjusting how Amperity handles certain types of semantic tags, changing the blocking strategy, adjusting the thresholds for match categories, updating the maximum number of allowed trivial duplicates.

In rare cases, adjustments may be made to how Amperity applies the results of blocking or to the clustering algorithm.
