Infrastructure at your Service
During the last DevOps Day in Geneva, I presented a sample of our CI implementation related to our MSSQL DMK maintenance product. It was definitely a very good experience for me and good opportunity to get feedback from DevOps community as well. During the session I explained our CI pipeline includes SQL Server containers both on AKS (K8s as managed service in Azure) and Windocks. I got questions from some of attendees who asked me…
It has been while since my last blog. Today it is about continuing with helm charts and how to upgrade / downgrade SQL Server containers to a specific cumulative update. My first write-up in my to-do list. Last year, I wrote an introduction of SQL Server containers on K8s. I remembered to face some issues when testing upgrade scenarios (probably a lack of knowledge). Since then, I have discovered helm charts and I use them…
Few days ago, a customer asks me if it is possible to move the history table to slower but cheaper storage. The question behind this is whether it is possible to create a history table on a separate filegroup and file. Few years ago, I write a serie of blogs about temporal table here. I will take the same example to try to set up a filegroup specific to a history table. In my sample,…
As encryption solution in SQL Server, Transparent Data Encryption (TDE) is simple and quick to set up. That’s why this is a common encryption mechanism. TDE encrypts data with a certificate at the page level, before SQL Server writes on the disk. It is supposed to protect your environment from some scenarios, where SQL Server files (backups or data) are stolen. By default the certificate used for encryption is stored in the master database. But…
Optimizing Multi-Billion Row Tables in Tabular in 2018 I wanted to attend the session moderated by Marco Russo to see his approach of optimizing performance in Tabular model The first thing to understand is how the data is stored and organized in a Tabular model. It is of course using the xVelocity in-memory capabilities with the Vertipac column storage layout engine. It organizes the data, compressing it by column, in combination with a dictionary…
The Microsoft data platform is evolving The third day began with the Keynote help by Rohan Kumar the Corporate Vice President of Azure Data by Microsoft The main message was “Hybrid data platform is the way for the future” and Microsoft is working in this direction. The use of AI and analytic to transform the customer business is also a key driver for the Microsoft data platform, which is building to enable this easily. Rohan…
After long hours of flights, Christophe Cosme and I finally arrived in Seattle at the SQL PASS Summit 2018. We picked up our badge and bag and now we are ready to begin… This first day for me started with the pre-conference about SQL Server Security with Denny Cherry. Many topics were discussed like: Network Designs (such as public IP vs. Private IP) Firewall configurations (such as Network Design between Public network, Internal network and…
A couple of weeks ago, Microsoft announced the first public CTP version of next SQL Server version (CTP2). It is not a surprise, the SQL Server vNext becomes SQL Server 2019 and there are a plenty of enhancements as well as new features to discover. But for now, let’s start with likely one of my favorites: availability groups on Kurbernetes (aka K8s). As far I may see from customers and hear from my colleagues as well,…
Few months ago, a customer asks me for finding in a column, how many rows exist with the same date & time and the delta between them. The column default value is based on the function CURRENT_TIMESTAMP and used as key as well. This is obviously a very bad idea but let’s go ahead… This anti pattern may lead to a lot of duplicate keys and the customer wanted to get a picture of the…
Few weeks ago, I have a little issue when I try to drop a database-user without login Unfortunately, I do a little mistake at the beginning… I receive like every morning a report if all AD logins (computers, groups, users) registered on SQL server instances are in the AD with the useful command sp_validatelogins This report indicates that a computer name dbi\server_name$ was no more in the AD. I drop the login without problem and…
