Cinchy Event Broker/CDC

Cinchy Change Data Capture Notifications

1. Overview

The Cinchy Event Broker/CDC (Change Data Capture) source allows you to capture data changes on your table and use these events in your data syncs.

Example Use Case: You want to set up a real-time sync between a Cinchy Table and Salesforce that updates Salesforce any time data is added, updated, or deleted on the Cinchy side. As long as you enable change notifications on your Cinchy table, you can do so by setting up a data sync and listener config with your source as the Cinchy Event Broker/CDC.

The Cinchy Event Broker/CDC supports both batch syncs and real-time syncs (most common).

Remember to set up your Listener Config if you are creating a real-time sync.

3. Source Tab

The following table outlines the mandatory and optional parameters you will find on the Source tab (Image 2).

Source Details

The following parameters will help to define your data sync source and how it functions.

Parameter	Description	Example
Source	Mandatory. Select your source from the drop down menu.	Cinchy Event Broker/CDC
Run Query	Optional. If true, executes a saved query, using the Cinchy ID of the changed record as a parameter. These query results are then used as the sync source, rather than using the Cinchy table where the data change originated. Review Appendix A for further details on this feature.

Schema

The Schema section is where you define which source columns you want to sync in your connection. You can repeat the values for multiple columns.

Parameter	Description	Example
Name	Mandatory. The name of your column as it appears in the source.	Name
Alias	Optional. You may choose to use an alias on your column so that it has a different name in the data sync.
Data Type	Mandatory. The data type of the column values.	Text
Description	Optional. You may choose to add a description to your column.

There are other options available for the Schema section if you click on Show Advanced.

Parameter	Description	Example
Mandatory	If both Mandatory and Validated are checked on a column, then rows where the column is empty are rejected If just Mandatory is checked on a column, then all rows are synced with the execution log status of failed, and the source error of "Mandatory Rule Violation" If just Validated is checked on a column, then all rows are synced.
Validate Data	If both Mandatory and Validated are checked on a column, then rows where the column is empty are rejected If just Validated is checked on a column, then all rows are synced.
Trim Whitespace	If your data type was chosen as "text", you can choose whether to trim the whitespace (that is, spaces and other non-printing characters).
Max Length

You can choose to add in a Transformation > String Replacement by inputting the following:

Parameter	Description	Example
Pattern	Mandatory if using a Transformation. The pattern for your string replacement, i.e. the string that will be searched and replaced.
Replacement	What you want to replace your pattern with.

Note that you can have more than one String Replacement

Filter

You have the option to add a source filter to your data sync. Please review the documentation here for more information on source filters.

Run Query

The Run Query parameter is available as an optional value for the Cinchy Event Broker/CDC connector. If set to true it executes a saved query; whichever record triggered the event becomes a parameter in that query. Thus the query now becomes the source instead of the table itself.

You are able to use any parameters defined in your listener config.

Example

In the below example, we have a data sync using the Event Broker/CDC as a source. Our Listener Config has been set with the CinchyID attribute (Image 4).

Image 4

We can enable the Run Query function to use the saved query "CDC Product Ticket Datestamps" as our source instead (Image 5). If we change the data from Record A in our source table to trigger our event, the Query Parameters below show that the Cinchy ID of Record A will be used in the query. This query is now our source.

Image 5

It would appear in the data sync config XML as follows:

  <CinchyEventBrokerDataSource runQuery="true" domain="Product" name="CDC Product Ticket Datestamp" parameters="{&quot;@id&quot;: &quot;Cinchy Id&quot; }">
