One of the most exciting new features in Azure Data Factory will be very familiar to data developers, data engineers and ETLers familiar with hand-coding data integration jobs or designing SSIS packages … “Control Flow” In general computer science terms, Control Flow is described as “the order in which individual statements, instructions or function calls of an imperative program are executed or evaluated,” (Wikipedia https://en.wikipedia.org/wiki/Control_flow). In the Microsoft Data Integration world, tools like SQL Server Integration Services (SSIS) enables control flow via tasks and containers (https://docs.microsoft.com/en-us/sql/integration-services/control-flow/control-flow). Azure Data Factory’s V1 service was focused on building sequenced pipelines for Big Data … Continue reading Control Flow Introduced in Azure Data Factory V2
If you’d like to try a quick & easy way to get up & running with your first V2 pipeline of Azure Data Factory, check out the video that I just recorded walking you through how to use the Azure Quickstart Template. To get to the template, you can search the Azure Quickstart template gallery, or here is a direct like to the ADF V2 template. Deploying this template to your Azure subscription will build a very simple ADF pipeline using the V2 public preview service, which was announced at the end of September at Ignite. The pipeline executes a … Continue reading Azure Data Factory V2 Quickstart Template
There are a lot of “best practice” and “performance guide” links available on the Internet to provide guidance on migrating SQL Server instances and databases from on-prem to Azure on VMs (aka Azure IaaS). In this post, I wanted to share a few findings from the field that I’ve encountered along the way recently working with customers on projects that migrate from on-prem SQL Server to Azure VMs. This is not a guide to migrating to Azure SQL Database and I do not cover all of the issues, migration steps or performance measures in an exhaustive manner. I will share … Continue reading SQL Server on Azure VMs – Updated Tips April 2017
