Parameters

Connection

Property

Type

Required

Default

Markup

Description

Connection

        

Indicates where user credentials and preferences should originate from. This is a design mode parameter used only during task construction and configuration, thus, comprises no markup. The available options are:

  • Host (default) - Specifies that user credentials and/or advanced preferences are configured individually for this activity. This option is normally chosen if only a single activity is required to complete an operation.

  • Session - Specifies that user credentials and/or advanced preferences are obtained from a pre-configured session created in a prior step with the use of the Azure Storage - Create session activity. This option is normally chosen if a combination of related activities are required to complete an operation. Linking several activities to a single session eliminates redundancy. Additionally, a single task supports construction and simultaneous execution of multiple sessions, improving efficiency.

Yes if connection is session-based

AzureStorageSession1

SESSION="MyAzureSession"

The name of an existing session to associate this activity with. This parameter is active only if the Connection parameter is set to Session. The default session name is 'AzureStorageSession1'.
