Microsoft Azure Data & AI Roadmap
Microsoft roadmap for data warehousing and Power BIWatch the On-Demand Webinar
If you have ever extracted data from an SAP system, you know it can quickly become a complex process. Transactional tables often contain millions or even billions of rows, and because the extraction process is a resource-intensive operation, daily processing of the entire dataset is usually impossible.
But no longer. Hitachi Solutions was part of a collaborative team that worked directly with Microsoft to design and implement a solution using the SAP Change Data Capture (CDC) connector. Now, on-premises SAP workloads can be re-powered in the Azure platform quickly, efficiently, and at scale. It’s a game changer for anyone who has struggled with the intricacies of extracting SAP data.
Why SAP users need it
Everyone wants more capability out of their data sources, especially SAP systems that contain the transactional and master data that are critical for daily operations. To get at that on-premises data for analysis, companies need to consolidate and move it to a cloud-based modern data estate.
There’s a massive benefit to efficiently moving SAP data to the cloud—it makes important core business data available for analysis by industry-leading innovations like data lakes, Power BI, artificial intelligence, and machine learning. When you have those tools available to use on your SAP data, you can generate holistic business insights that can improve and accelerate business decision-making.
How it works
The SAP CDC solution in Azure Data Factory or Azure Synapse is a connector between SAP and Azure. It’s an efficient way to extract and process core SAP data from a wide range of source objects, making it an ideal invaluable tool for modern data analytics in an Azure environment.
The SAP side
The SAP ODP connector invokes the SAP Operational Data Provisioning API over standard Remote Function Call (RFC) modules to extract SAP transaction and master data, modeling the data and making it available for search. The CDC process monitors the delta in the source database and moves it downstream in real time to Azure. It specifically tracks the INSERT, UPDATE, and DELETE transactions performed on a table to capture data changes.
The Azure side
Once data is moved to Azure Data Factory or Azure Synapse, you’ll need to set up a pipeline and build the mapping data flow to transform and load the SAP data into a supported data store. The supported stores include Azure Data Lake Storage Gen2 or other databases like an Azure SQL Database. When results are loaded into a Data Lake Storage Gen2 in delta lake format, they can be queried using Synapse serverless SQL, Synapse Dedicated via Polybase, and Apache Spark pools. This flexibility lets data analysts and scientists work with data in a way that suits their needs and expertise.
Here’s a simplified diagram of the architecture:
Working with changed data only reduces resource consumption and provides a tremendous efficiency boost in high data volume scenarios with cleaner, more organized data management and governance. Before now, if you wanted to do this in an Azure Data Factory pipeline, you had to create complex logic that used watermarks to select relevant data, easily adding about 30 percent more time to the effort.
