Data Rules vs Sync Rules

Data rules are a combination and (ACLs), specified in a single XML document. If your app is currently using , we recommend migrating to data rules. Please see which outlines the migration process.

Details matter with data rules

Data rules is an advanced feature where implementation details can have a significant impact on , sync performance, as well as the design of your .

Please be sure to understand the constraints and implications of your data rules before deploying them to an environment with active users.

Overview

Data rules allow developers to determine programmatically (1) what data should sync to devices for offline access, and (2) what kind of read and write access a user should have to data (applies to online and offline access).

To define data rules, you need to understand the concept of data buckets:

To limit data synched to devices, developers can specify sync rules. Read more about sync rules here:

To limit user read/write access to data (whether that data is on the user's device or accessed via ), developers can specify data ACLs. Read more about them here:

Data rules combine the above two objectives by letting developers specify both sync rules and data ACLs in one XML file, namely data_rules.xml, which is available in OXIDE once your app has data rules enabled.
