Looking to register all the Data Sources in a subscription/account but the option for "Azure (Multiple Sources)" is missing. As are other sources (HIVE, SAP, AWS S3).
Why would this be the case?
Unfortunately, Azure Purview does not support (HIVE, SAP, AWS S3) as data sources.
Azure Purview supports the following data sources:
SQL server on-premises
Azure Data Lake Storage Gen1
Azure Data Lake Storage Gen2
Azure Blob Storage
Azure Data Explorer
Azure SQL DB
Azure SQL DB Managed Instance
Azure Synapse Analytics (formerly SQL DW)
Azure Cosmos DB
Power BI
