From the navigation pane, select Data factories and open it. Click the “Author & Monitor” pane. For example, an Azure Storage-linked service specifies a connection string to connect to the Azure Storage account. The presentation spends some time on Data Factory components including pipelines, dataflows and triggers. Think of it this way: a linked service defines the connection to the data source, and a dataset represents the structure of the data. Linked services are much like connection strings, which define the connection information that's needed for Data Factory to connect to external resources. The following points apply to update of existing TriggerResource elements: In case of pipeline failures, tumbling window trigger can retry the execution of the referenced pipeline automatically, using the same input parameters, without the user intervention. Currently, this behavior can't be modified. A tumbling window trigger has a one-to-one relationship with a pipeline and can only reference a singular pipeline. Pipeline runs are typically instantiated by passing the arguments to the parameters that are defined in pipelines. For example, imagine a gaming company that collects petabytes of game logs that are produced by games in the cloud. With Data Factory, you can use the Copy Activity in a data pipeline to move data from both on-premises and cloud source data stores to a centralization data store in the cloud for further analysis.
