Apps can store data in the form of entity properties in Confluence. Entity properties are
key-value pairs where the key is a string used to identify the property in all operations, and the
value is a JSON blob. Confluence allows properties to be stored on Confluence pages with
content properties or on the app itself with app properties.
Your app will need to request the right scopes to perform operations
on entity properties.
Hosted data storage is useful to Atlassian Connect developers for the following reasons:
without any need for an application server. Your data will be stored against the host application
Imports and exports are handled by the host product. Since your data is stored with the host application it is included in the host applications
backups. This means that the import process will restore your data automatically. With entity
properties you never need to worry about your data being lost or disconnected from the customer.
Conditions can be predicated on entity properties. You can configure whether a web fragment will be shown based on the value of an entity property.
The products have access to your properties. This means that you can write CQL queries based on content properties. This
enables your users to enjoy the power of CQL on search data that you have defined.
Users can access entity and app properties using the REST APIs. For this reason, never store user data or privileged configuration information using entity properties or app properties.
You can use CQL to query content properties
in your Confluence instance. For example, an app could store the number of likes on a page in a content property, then
by creating an index schema module for that property you can query the values to see how many pieces of content have
more than 20 likes.
