Note: I'll be focusing on Azure Cloud and SQL Server, but these considerations are valid for any Cloud/DB Vendor. Whenever people talk about “The Cloud” I often hear: “cloud is expensive” and, sooner or later, “if performance aren’t good we can scale up in minutes later” .The mindset of taking care of performance issue by scaling up/down cloud resources...
Machine learning is the buzzword of the moment, so I wanted to talk about that sweet ML here too. For a project that I’m working on, I’ve been experimenting on basic ML prediction algorithms, in this instance I’ll show you a basic POC on how ML can be integrated right into PowerBI in a serviceable manner. It’s ugly but it works The data I just needed some whatever data to...
Since about a couple of versions ago, Azure Data Studio introduced Jupyter Notebooks support for SQL Server (and with SQL Server 2019 “Big Data Clusters” on the horizon, it was about time) What are Notebooks? “Notebooks” are a tool that our data science/machine learning colleagues know, love and are at their disposal since some time (Python, Spark, etc…); A notebook...
Recently I had to look up the definition for a bunch of SQL objects and didn’t want to manually retrieve them manually in SSMS (with Create Scripts) or Visual Studio (by searching the object name in my TFS repository). Since lazyness and automation are the basis of a well done engineering work, I wanted to create a list, where I could basically click on the object that I needed and see the...
Working with strings in SQL Server isn’t as easy or powerful as using any programming language, but, I’m sure that more than once you had to to some data manipulation directly in the database, this may help you out, and it doesn’t use Loops, CLR or XML The idea is to exploit set logic, as opposed to the classic program logic of when you’re usually playing with strings in...
in some projects I have a lot of Dynamic SQL going on, some queries are fast, some queries are slow, it depends on how the dynamic statement is actually put together ¯\_(ツ)_/¯ Tracking the performance of such statements is usually difficult because you don’t really know “why it’s slow” and you have to interpolate data from the app and the plan cache (if the plan is still...
Most of the support request I get involved with can be summarized with the following keywords: “slow” + “datawarehouse” + “ETL” + “Save us” What about thinking about ETL performance before it goes bad? Before the system is in production for some time , the data size reaches a decent size which wasn’t tested in DEV and you find out that the...
