You can use Unified Storage Connector to connect AEM Forms to external data storages.
For example, you can fill values for fields in an adaptive form and submit it to an AEM Workflow. You can further configure AEM Workflows to store data in an external storage, such as the Microsoft Azure storage server. Use the Unified Storage Connector to create a connection between AEM Workflows and the external storage.
Create an Azure storage configuration and refer to that configuration using the Unified Storage Connector. You can then configure AEM Workflow models to externalize the data storage to connect them to an Azure storage server.
Before executing these steps, ensure that you have an Azure storage account and an access key to authorize the access to the Azure storage account.
Perform the following steps to create an Azure storage configuration:
Perform the following steps to configure Unified Storage Connector for AEM Workflows:
Navigate to Tools > Forms > Unified Storage Connector.
In the Workflow section, Select Azure from the Storage drop-down list.
Specify the configuration path for the Azure storage configuration in the Storage Configuration Path field.
Tap Publish and then tap Save to save the configuration.
Perform the following steps to configure an AEM Workflow model for an external data storage:
The options to save the Assign Task step as draft and to retrieve the history of the Assign Task step are disabled when you configure an AEM workflow model for external data storage.
The following are the guidelines when you are using AEM Workflows and storing data to external data storages, such as Microsoft Azure storage server:
Use variables to store data while defining input and output data files and attachments in workflow model steps. Do not select Relative to Payload and Available at an absolute path options. The Relative to Payload and Available at an absolute path options do not display automatically once you configure an AEM Workflow model for external data storage.
Use variables to store data file and attachments while submitting an adaptive form to an AEM Workflow. Do not select Relative to Payload option while submitting an adaptive form to an AEM Workflow. The Relative to Payload option do not display automatically once you configure an AEM Workflow model for external data storage.
Do not use a custom AEM Workflow step in a workflow model to store data in the CRX DE repository.
When you configure an AEM Workflow model for external data storage, do not create custom columns for AEM Inbox since the values of the custom columns are not fetched if the workitem in the AEM Inbox belongs to a workflow that is marked for external storage.
