You have an Azure Data Lake Storage account that contains a staging zone.

You need to design a daily process to ingest incremental data from the staging zone, transform the data by executing an R script, and then insert the transformed data into a data warehouse in Azure Synapse Analytics.

Solution: You use an Azure Data Factory schedule trigger to execute a pipeline that executes mapping data flow, and then inserts the data into the data warehouse.

Does this meet the goal?

Show Suggested Answer Hide Answer
Suggested Answer: B

If you need to transform data in a way that is not supported by Data Factory, you can create a custom activity,

not a mapping flow,5 with your own data processing logic and use the activity in the pipeline. You can create a

custom activity to run R scripts on your HDInsight cluster with R installed.
