There are a few server-wide configurations that you cannot setup during inital Big Data Cluster deployment. One of those is enabling SQL Agent service. That’s right. If you have deployed a Big Data Cluster you will notice the SQL Server Agent is disabled by default (see screenshot below):
In my previous posts, I showed you how to deploy a single node cluster and a multi-node cluster. That’s find and dandy but how do you upgrade to the newest SQL Server CU? This blog post will show you how to easily upgrade a SQL Server Big Data Cluster. This method applies to a single node or multi-node cluster. It does not matter how many nodes your BDC has, this upgrade process will work.
In my previous post, I talked about deploying a Big Data Cluster on a single node Kubernetes cluster. That’s cool and all but what if you’re a business or organization that cannot have your data on the cloud for whatever reason? Is there a way to deploy a Big Data Cluster on-premise? Absolutely! I’ll walk you through setting that up this blog post. I will walk you through deploying a 3-node Kubernetes cluster, then deploying a Big Data Cluster on top of that.
One of my 2020 goals was to start presenting more. The easiest, and most cost efficient, way to do that is by presenting remotely. Another goal I had was to start creating Big Data Cluster videos for my YouTube channel. These two goals required a different set of tools. I also had no idea how complicated video recording could get. I finally got everything setup the way I want and a few friends asked me about my setup. This blog post will list everything I use and lessons learned.
So you want to play around with a Big Data Cluster but on a strict budget? No problem! Keep reading or watch the video below.
If you are interested in deploying a Big Data Cluster on a multi-node kubeadm cluster, check out my post here.
One of the key components of a Big Data Cluster is the data pool. Within that single data pool, there are two SQL Server instances. The primary job of the data pool is to provide data persistence and caching for the Big Data Cluster. (At the time of this blog post, there can only be a single data pool in a Big Data Cluster and the maximum supported number instances in a data pool is eight.) The instances inside the data pool do not communicate with each other and are accessed via the SQL Server Master instance. The data pool instances are also where data marts are created.
HAPPY NEW YEAR!
Wow! Time flies by so fast! I can’t believe it’s 2020. I’ve been posting these “blog stats” for a couple years now and it’s always been bittersweet when I post them. On one hand it reminds me that time is moving so fast (and it some cases I want it to slow down a bit). On the other hand I get to reflect on the year that past and be grateful for all the beautiful things that happened in my life.
Below is a recap of 2019: Continue reading “Blog Stats – 2019”
Instead of boring you with content that you can easily find on Amazon, I will do something different this review post. I will give you the three reasons why I recommend this book for SQL DBAs and data professionals. It doesn’t matter if you are a beginner or an expert. This book will be a great addition to your library regardless of your level of SQL Server knowledge.
A few months ago I posted a blog on deploying a BDC using the built-in ADS notebook. This blog post will go a bit deeper into deploying a Big Data Cluster on AKS (Azure Kubernetes Service) using Azure Data Studio (version 1.13.0). In addition, I’ll go over the pros and cons and dive deeper into the reasons why I recommend going with AKS for your Big Data Cluster deployments.
One of the biggest questions I had when I first started diving into Big Data Clusters was, “What about licensing….how will that work?” With so many different instances running on the storage pool, data pool and compute pool nodes will licensing cost too much? The answer I got from Microsoft was that it will “be competitive”.
Before you deploy big data clusters, you must configure the tools below on a Windows or Linux machine that will act like a “base machine” from which you will be able to deploy, manage, and monitor a SQL Server Big Data Cluster. For the example in this blog I will use a virtual machine running Windows Server 2016 running 4 cores and 8 GB RAM. (This can also work on a Windows 10 Pro machine as well).
A few months ago I posted a blog on deploying a BDC using the built-in ADS notebook. This blog post will talk about the deployment options available for Big Data Clusters and benefits of going with Azure Kubernetes Service (AKS).
I love to share real-life stories when I give talks. I usually start out my sessions with a story on how I got interested in Big Data Clusters. It all starts with my neighbor Tom (not his real name) last year (2018). I was at the bus stop with my 5 yr old son on his first day of Kindergarten. As I am waiting patiently for the bus to arrive I hear a voice say,
“Are you in IT?”
I finally presented my first tech at SQL Saturday Sioux Falls and Baton Rouge. I decided to name my session, “Big Data Clusters for the Absolute Beginner” because beginning of 2019 I *was* the absolute beginner (and I’m learning every day!) So in a way, my session is “based on a true story” :) I’m super-excited because I think it’s the future of SQL Server. Big Data Clusters are new and cutting-edge technology.
