To this point, I have focused my Polybase series on interactions with on-premises Hadoop, as it’s the use case most apropos to me. I want to start expanding that out to include other interaction mechanisms, and I’m going to start with one of the easiest: Azure Blob Storage.
Ayman El-Ghazali has a great blog post the topic, which he turned into a full-length talk. As such, this post will fill in the gaps rather than start from scratch. In today’s post, my intention is to retrieve data from Azure Blob Storage and get an idea of what’s happening. From there, we’ll spend a couple more posts on Azure Blob Storage, looking a bit deeper into the process. That said, my expectation going into this series is that much of what we do with Azure Blob Storage will mimic what we did with Hadoop, as there are no Polybase core concepts unique to Azure Blob Storage, at least any of which I am aware.
Spoilers: I’m still not aware of any core concepts unique to Azure Blob Storage.
