Distributed Tables in Azure Synapse SQL


Azure Synapse is the new Generation of SQL DW (Azure SQL Data Warehouse), that is launched in the past year In November 2019 the First announced for Azure SQL Synapse was in Microsoft Ignite 2019, With Azure Synapse you can bring together cloud data warehousing and big data analytics into a single service platform, Azure Synapse is massively parallel processing (MPP) Engine. Microsoft Added on it many features, With Azure, Synapse Compute is separate from storage, this means you can scale compute independently for the data in your System (APP), With Azure synapse, you can bring the relational Data and Non-relational data together in one place and easily you can do your query and your analytics on a huge amount of information, Azure Synapse build for a massive parallel query for Analytics not for transaction database, Azure Synapse uses Azure Data Lake Storage Gen2 for more information About Azure Data Lake Gen2 Check this Post, Azure Synapse Support (Apache Spark integration, Power BI, Azure ML), Also you can take a look to this demo with Rohan Kumar this demo is part from Microsoft Ignite 2019 Keynote and you can Follow Rohan Posts from here
