Using Azure Key Vault with Azure Databricks

Published 2020-03-26 by Kevin Feasel

Jason Bonello shows how easy it is to integrate Azure Key Vault into Azure Databricks:

In Azure Key Vault we will be adding secrets that we will be calling through Azure Databricks within the notebooks. First and foremost, this is for security purposes. It will ensure usernames and passwords are not hardcoded within the notebook cells and offer some type of control over access in case it needs to be reverted later on (assuming it is controlled by a different administrator). In addition to this, it will offer a better way of maintaining a solution, since if a password ever needs to be changed, it will only be changed in the Azure Key Vault without the need to go through any notebooks or logic.

If you don’t use Key Vault, Databricks does include its own secrets storage, so there’s really no reason to keep them in plaintext.

Working with Spark.Net on Azure Synapse Analytics

Published 2020-03-26 by Kevin Feasel

Paul Andrew takes a look at Spark.NET (or Spark.Net or dotnet-spark or however I’m calling it this time):

The main reason I wanted access to Synapse is to play around with Spark.Net via the Synapse workspace Notebooks. Currently if deploying Synapse via the public Azure portal you only get the option to create a SQL compute pool, formally known as an Azure SQLDW. While this is good, it gives us none of the exciting things that we were shown about Synapse back in November last year during the Microsoft Ignite conference.

To get the good stuff in Azure Synapse Analytics you need access to the full developer UI and Synapse Workspace.

Max Trinidad gives us a primer on SMO with Powershell 7:

There are two ways you could use SMO in PowerShell 7 (cross-platform):

1. Installing the SMO NuGet packages, two packages are requiered:
a. Microsoft.SqlServer.SqlManagementObjects Version 150.18208.0 (as of 03/23/2020)
b. Microsoft.Data.SqlClient Version 1.1.1 (recommended)

2. Installing the PowerShell Module: SqlServer Version 21.1.18221 (as of 03/23/2020)

Using relog to Make PerfMon Better

Published 2020-03-26 by Kevin Feasel

Erin Stellato shows us how to use relog:

Today I had to remember the steps for using relog. If you’ve never heard of relog, stay with me. It’s a tool for merging PerfMon files, and also for extracting smaller data sets from Perfmon. I still love PerfMon friends, I admit it. It’s been a staple for understanding performance on a Windows Server since I’ve started in IT. But I haven’t used relog in forever so I completely forgot the commands I needed.

sqltxls Now Supported Cross-Platform

Published 2020-03-26 by Kevin Feasel

Randolph West has made sql2xls work on Linux and MacOS:

Last year I released sql2xls, a free open-source tool which lets you throw a bunch of scripts into a folder, run them automatically against SQL Server and get the results back in a nicely-formatted Excel file, one tab per script.

A year later, I am happy to announce that the tool now runs cross-platform. You can compile and run it with .NET Core 3.1 LTS to run on Windows, macOS, and Linux. It uses the new Microsoft.Data.SqlClient library from NuGet, as well as the latest beta of ClosedXML.

Read on for a few more tips and go check the project out.

Getting SQL Server with Current Linux Distributions

Published 2020-03-26 by Kevin Feasel

Tejas Shah announces the availability of SQL Server 2019 on the latest long-term releases of Ubuntu, Red Hat, and SuSE:

SQL Server team has been working diligently in adding support for current Linux distributions. To this end, the team announced support for SQL Server 2019 on RHEL 8.0, Ubuntu 18.04 and SLES 12 SP5 within last quarter.

The team is glad to announce that the Azure marketplace PAYG (Pay As You Go) images for SQL Server 2019 on RHEL 8.0, Ubuntu 18.04 and SLES 12 SP5 have been made generally available. You can deploy these images to get the latest of both SQL Server 2019 functionality and operating system improvements.

With Ubuntu 20.04 coming out soon, it’ll be interesting to see when that officially becomes supported.
