One way sync

General Q&A
1

Is there a way to sync records one way from the device to the Journey back end with sync rules?
For example we only create records and never read them for a specific object on the mobile.
Ideally, after the records have been created and synced to the Journey backend, we want them to be desynced from the device.

Hi @alex ,

It is possible to sync records one way from the device to the Journey back end. I will use the location and product model below to explain the logic.

schema.xml

<model name="location" label="Location">
    <field name="archived" label="Archived" type="boolean" />
    <field name="name" label="Name" type="text" />
        
    <display>{name}</display>
</model>

<model name="product" label="Product">
    <field name="archived" label="Archived" type="boolean" />
    <field name="name" label="Name" type="text" />
        
    <display>{name}</display>
</model>

Data created on a device will automatically sync to our servers. To prevent certain objects from syncing back to devices you can do the following:

1. Do not include the model in any of your sync buckets.

In the code snippet below, only the location objects will sync to devices. Because product is not included in the sync rules, it will not sync to devices.

sync_rules.xml

<global-bucket>
    <model name="location" />
</global-bucket>

2. Sync data based on a certain condition.

If you have a scenario where you have some archived product objects and would only like to sync product objects that have not been archived to users’ devices, you can add a condition as shown below:

sync_rules.xml

<global-bucket>
    <model name="location" />
    <model name="product" condition="archived != true"/>
</global-bucket>
