Loading Azure Synapse Analytics using PolyBase

Gauri Mahajan needs to load some data:

Azure Synapse Analytics is Microsoft’s data warehousing offering on Azure Cloud. It supports three types of runtimes – SQL Serverless Pool, SQL Dedicated Pool, and Spark Pools. As there are a variety of data sources on Azure, it’s very obvious that there can be varying types and volumes of data that would have to be loaded into Azure Synapse pools. There are three major types of data ingestion approaches that can be used to load data into Synapse. The COPY command is the most flexible and elaborate mechanism, where someone can execute this command from a SQL pool to load data from supported data repositories. This command is convenient to load ad-hoc and small to medium-sized data loads into Synapse. The second method of loading data is the Bulk Insert, where the method name is self-relevant regarding the approach functionality. To ingest the data from supported repositories into dedicated SQL pools, PolyBase is as efficient and at times it’s even more efficient than the COPY command. This article will help you understand the process to ingest data into Azure Synapse Analytics using PolyBase to load the data.
