Access external data from Azure Synapse Analytics using Polybase


Introduction

Azure synapse analytics supports many data loading methods for accessing data stored in the external sources. In my previous articles, Loading data in Azure Synapse using Copy and Loading data in Azure Synapse Analytics using Azure Data Factory, I have discussed about Azure Synapse Analytics and data loading using Copy command and Azure Data Factory (ADF).

In this article, I will discuss the Polybase technique and how it can be used to access data stored in Azure Blob Storage and Azure Data Lake storage.

Polybase

Polybase is a technology that accesses external data stored in Azure Blob storage, Hadoop, or
