We’ve just published a new article in the SQL docs, Tune nonclustered indexes with missing index suggestions . The article explains what the missing index feature is, limitations of the feature, and how to use missing index DMVs and missing index suggestions in Query Store to tune indexes.
During a discussion of troubleshooting query timeouts in Azure SQL Database recently, I thought – hey, I wonder if you can find queries that timed out in Query Store?
Turns out, you can.
We’ve recently updated the SQL Server and Azure SQL index architecture and design guide. This article is an in-depth guide to indexing in databases using the SQL Server engine, including SQL Server, Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics.
Our recent update adds a table to categorize the types of indexes discussed in the article, clarifies B-trees vs B+ trees, and describes how row locators (aka “secret columns”) are used in nonclustered indexes.
I’d like to openly and honestly answer the rumors that I have been removed from the Microsoft MVP program.
Have you ever tried to create an object in SQL Server, but it failed due to a missing table, column, or other dependency? If so, you’ve hit a case where SQL Server doesn’t offer ‘deferred name resolution’.
When I woke up today in the UK, Twitter was alive with jokes, hot takes, and sympathy about an email sent out to millions of folks on a contact list for HBO Max featuring the subject line, “Integration Test Email #1”.
One big gotcha that teams often encounter when automating deployments for databases is that it’s difficult– or sometimes impossible – to ensure that all changes to the production database are performed through the automation pipeline.
These out-of-band changes case the production database to “drift” away from the schema as defined in version control.
A call for speakers is open for the very first edition of the Dativerse conference, which will be held on August 13, 2021: http://dativerse.io/
I’ll be giving a 10 minute lightning talk at the upcoming Mental Health and Wellness day event on May 7, 2021, hosted by the Data Platform WIT group.
Amid the global pandemic, online tech conferences have had a natural surge in popularity. I’ve attended quite a few of these in 2020 across several technical areas (database tech, DevOps, privacy, tech research). The conferences have been both large and small, both free and paid, and have been held across a few different regions and time zones.
It’s Down Tools Week at Redgate.
In this episode, I share what “Down Tools Week” is, what I’m working on this week, and why I think it’s a terrific experience for fostering creativity, innovation, and teamwork. In closing I share some thoughts on variations of this kind of project which you might use in your own organization.
Many people use entrenched processes for database development that have been in place so long that it’s hard to imagine doing it any other way. In this episode, I share three things that should NOT be normal for database development– but which are incredibly common.
Learning Git can be daunting for DBAs. In this 20 minute episode, I discuss why learning a VCS is necessary for DBAs, then give three tips on scoping your project, choosing the right tools, and making sure the project is successful.
I’ve begun working on developing a couple of small habits this month, thanks largely to Andy Mallon’s helpful advocacy.
I’m excited to begin moving over courses from SQL Workbooks and making the material available here. The first course up for grabs is The Dirty Secrets of NOLOCK.
I’m working on a project where it’s useful to automate environment setup and teardown for testing some devops deployment scenarios for databases using transactional replication.
Following on from my Learner’s Guide to SQL Server Performance Triage, I’m tackling Query Tuning. In this guide, I’m experimenting with an outline style rather than expanding each paragraph.
