Customized Per-User Default Values in Power BI

Published 2021-07-20 by Kevin Feasel

Marco Russo and Alberto Ferrari lay out a challenge:

Tabular offers the built-in feature of hiding rows of data from specific users. For example, you can create a set of security rules to let a store manager see only the sales of their store. This works fine if your goal is to secure data, which means preventing access to data that a user is not expected to see.

Another common requirement is to be able to select by default, for a store manager, their sales. With that said, store managers can see the data of other stores, but they need to explicitly request it. In other words: by default, the store manager sees the sales of their store only. By using a slicer, they can choose a different combination of stores.

Read on for the solution, but be sure to read the warnings Marco and Alberto include near the end of the article.

Filtering Extended Events with Actions

Published 2021-07-20 by Kevin Feasel

Grant Fritchey gives us a technique to filter extended events:

Did you know, you can use Actions to Filter Extended Events? Well, you can. Filtering is one of the greatest ways in which Extended Events differentiates itself from other mechanisms of gathering information about the behavior of SQL Server. You can put Actions to work in your filtering. Best of all, the Actions don’t have to be collected in order to put them to work filtering your Extend Events.

Read on to see how.

Log Shipping Configuration with Powershell

Published 2021-07-20 by Kevin Feasel

Lee Markum needs to do log shipping in bulk:

I recently needed to configure log shipping for multiple databases at once as part of a migration project. I turned to PowerShell to do this.

But before we get to that part, this post assumes that you’ve done the upfront work to create shares for the backups to write to and for the backups to be copied to. This will involve providing the right permissions for the SQL Server service accounts involved in Log Shipping. If you are not familiar with this, that’s perfectly fine. Check out this article in MS Docs first.

Parameterizing ADF Pipelines

Published 2021-07-19 by Kevin Feasel

Reitse Eskens continues a series on learning Azure Data Factory:

In my previous blog I created the integration runtimes, and the linked services. However, we need to create new datasets. If you remember, and I don’t blame you if you don’t, the dataset I created contained a reference to a table. That’s nice, but this time we don’t want just one table, we want a number of tables.

Managing Spatial Data in Azure

Published 2021-07-19 by Kevin Feasel

Rolf Tesmer takes us through the different Azure services which offer some ability to work with spatial data:

Every now and then you come across a use-case where you need to do something with spatial data, and you need to do it in the cloud (Azure, of course)! Up until that very point you maybe didn’t know, or perhaps even care, much about the intricacies of spatial data assets, let alone how the heck you were going to store it, process it, and query it, without making a mess of your current data stack.

Well, if you’re that person, then I say welcome to this blog post!

Click through for a fairly lengthy list, including Rolf’s comments on each. Also note the one big omission from the list as far as data platform products.

The Downside Risk of Index Hints

Published 2021-07-19 by Kevin Feasel

Chad Callihan explains why you should be careful before deploying code which uses index hints:

This might be good enough…for now. The potential issues with index hints can be more about the future than the present. You might come along later on and think “why not use an index to cover the whole query?” We can add the index:

But if our query is still written to include the index hint (in a stored procedure for example) the new index is not going to matter. The old index is still forced to be used. Even if something better comes along, you’re going to need to modify the query in addition to adding the better index. If an index was added for a completely separate query but would also be an improvement for the query in question, it’s also not going to get by the index hint.

Click through for additional problems which can crop up as you use index hints. This isn’t a big argument against using them at all, but rather understanding (and remembering!) where you do use them and making sure that’s communicated well to the entire team, including future you.

A Wish List for SQL Server Monitoring

Published 2021-07-16 by Kevin Feasel

Chris Shaw lays out some of the problems with monitoring systems today:

A next-generation monitoring tool should not just provide the same standard old dashboard dressed up with new fancy graphs; it should empower me to be actionable. It needs to help me improve the environment and show me the impacts of those actions on the system, and thus, the business.

What the industry needs (for risk of rendering the title of this article bunk) is not another monitoring tool. I have tools that help me monitor and they do a fine job of specifically doing that.  I need a tool that will take me into the future, I need a tool that makes me better and faster at what I do.  This industry needs a smarter tool.

Click through to see what Chris has in mind, though the reason you haven’t seen some of this stuff is that it’s a couple orders of magnitude more difficult than what we do see in monitoring solutions. H/T Amanda White.
