Azure SQL DB Serverless for Hyperscale now GA

Published 2024-02-15 by Kevin Feasel

Morgan Oslake has an announcement:

Optimizing resource allocation to achieve performance goals while controlling costs can be a challenging balance to strike especially for database workloads with complex usage patterns.  Azure SQL Database serverless provides a solution to help address these challenges, but until now the general availability of serverless has only been available in the General Purpose tier.  However, many workloads that can benefit from serverless may require greater performance and scale along with other capabilities unique to the Hyperscale tier.

We are pleased to announce the general availability of serverless auto-scaling for Hyperscale in Azure SQL Database.  The benefits of serverless and Hyperscale now come together into a single database solution.

Read on to see what this means for you and how it can change the billing strategy around Hyperscale.

The Tradeoffs of Azure SQL Managed Instance General Purpose

Published 2024-01-23 by Kevin Feasel

Kendra Little provides some guidance:

Whether or not you use Azure SQL Managed Instance, you will likely be asked for an opinion on it eventually if you’re a SQL Server person.

While the architecture is documented, it can be a bit of a long read and some of the gotchas are spread out over different pages – so I’m drawing up the architecture of each service tier along with notable implications for the design on performance and cost. Here’s the scoop on General Purpose.

What’s New in .NET 8

Published 2023-12-28 by Kevin Feasel

Thao Nguyen keeps us up to date on .NET:

Microsoft has announced .NET 8 recently. It emphasized the cloud, performance, full-stack Blazor and .NET MAUI as major highlights of the latest edition of the company’s free, cross-platform, open-source developer platform.

Of special importance to enterprises, .NET 8 is a long-term support (LTS), which means it will be supported and patched for three years as opposed to 18 months for a standard term support (STS) release.

Click through for the list, as it’s good to keep at least one eye on the developers lest they run around unopposed.

Database Compatibility Levels and SQL Server Versions

Published 2023-12-20 by Kevin Feasel

Kendra Little demands change:

According to Microsoft’s documentation, “Database compatibility level … allow[s] the SQL Server Database Engine to be upgraded while keeping the same functional status for connecting applications by maintaining the same pre-upgrade database compatibility level.”

But these days, the “functional status” of a database at a given compatibility level differs depending on whether you’re using SQL Server, Azure SQL Managed Instance, or Azure SQL Database – and in the hosted versions it may change anytime without notice. Surprise, your database behaves differently now!

The whole concept is breaking down, and this is bad news for users of both managed services and the boxed product.

What’s Missing in Azure SQL Managed Instance?

Published 2023-12-15 by Kevin Feasel

Kendra Little gives us the lowdown:

Spoiler: a large amount of features from SQL Server 2022 are missing from Azure SQL Managed Instance. Some major features are missing that were introduced in SQL Server 2019– and here we are just a few weeks away from 2024.

But Microsoft’s top-line marketing claims about Azure SQL Managed Instance remain that “it’s always up to date with the latest SQL features and functionality.”

Let’s dig into some of the documented highlights on missing features, so you can decide for yourself what to think of that statement.

Read on for Kendra’s take. I agree with the overall argument: Managed Instance is an expensive service intended to serve as a SQL Server replacement. But there’s still a lot missing from the product and it still feels like it’s smarter simply to build a VM running SQL Server rather than play the Managed Instance game. Azure SQL DB I extend a bit more grace toward, as its intent is a bit different from the SQL Server box product or Managed Instance.

Azure Data Studio 1.47 Now Available

Another change that is sure to be noticed is that we have enabled parallel message processing by default. This change will improve the performance of the application when connected to SQL Server data sources. We have introduced two new settings to manage this new behavior. The first setting, Mssql: Parallel Message Processing is set to true by default. The other setting, Mssql: Parallel Message Processing Limit, has a default of 100. This setting controls the number of threads used for parallel processing. We are excited to hear your impressions on the impact of this change.

Apache Zookeeper Vulnerability

Published 2023-10-24 by Kevin Feasel

The Instaclustr team reviews an announcement:

On October 11, 2023, the Apache ZooKeeper™ project announced that a security vulnerability has been identified in Apache ZooKeeper, CVE-2023-44981. The Apache ZooKeeper project has classified the severity of this CVE as critical. The CVSS (Common Vulnerability Scoring System) 3.x severity rating for this vulnerability by the NVD (National Vulnerability Database) is base score 9.1 Critical.  

That’s a rather high base score and is comes about if you have the setting quorum.auth.enableSasl=true. Updating to the Zookeeper 3.7.2 or alter, 3.8.3 or later, or anything in the 3.9 branch will fix this vulnerability.
