As we can add Data Factory project for ADF version1. Can we add project for ADF version2 and if yes how can we do that? Whenever I am trying to add Data Factory Project it gives me option for version1 and not for version2. Is there anyway to add ADF version2 project to my solution?
Things have changed when we talk & work on ADF V1 and V2. I am presuming when you are saying ADFV1 project in VS you used to create empty project for data integration solution where you had to create linked services, datasets & pipelines based on the defined template - json format.
Now from ADFV2 on wards if you want to code ADFV2 in C# you can simply create a console application and code your way through ADFV2. Likewise if you choose other programming methods the way to do it changes.
For more detailed reference please have a look at the complete ADFV2 documentation.

I'm trying to build a ML pipeline using Alteryx. I'll be pulling data via API and build an automated workflow. But first, until I get license and make sure, I'd like to use flat files to build the pipeline. The data in flat files and data from API (batch) would essentially be the same. Can I develop the full pipeline first and then swap the ingestion portion later with API connector?
I have searched online but haven't found an answer to this.
I am learning azure data factory and would really like to do its development in Visual studio environment. I have VS 2019 installed on my machine and I don't see an option to develop ADF in it.
Is there any version of VS that ADF can be developed in or we are right now stuck with developing it in web UI for the time?
I know BI development tools needed additional plug in to VS environment to work. Does ADF need something similar to that too.
If not, how can we back up our work done in web ADF. Is there an option to link it somehow with the azure repo or GIT?
Starting with ADF V2, development is really intended to be done completely in the web interface. I had the same question as you at the time, but now the web tools are quite good and I don't give it a second thought. While I'm sure there are other options for developing and deploying the ARM templates, do yourself a favor and use the web UI.
By default, Data Factory only saves code changes on "Publish". An optional configuration allows source control via Git integration. You can use either either Azure DevOps or Github. I highly recommend this approach, even if you only ever work in the main branch (fine for lone developers, a bad idea for collaboration). In this case, Publish takes the current state of the main branch and surfaces your artifacts to the ADF service. That means you will still need to Publish for your changes to be live.
NOTE: Git integration is also supported in Azure Synapse, where it has tremendous value for collaboration across a wide variety of artifact types.
I have some pipelines which I want to move from one data factory to another. Is there any possible way to migrate them?
The easiest way to do this is to just pull the git repo for the source factory down to your local file system and then just copy and paste the desired files into your destination factory folder structure. That's it.
Alternatively, you can do this through the ADF editor by creating a shell of the pipeline in the target factory first, then go to the source factory and switch to the code view for that pipeline, copy and paste that code into the target pipeline shell you created, and then save from there.
A pipeline is just json. You may need to copy the dependent objects also, but those are done the exact same way.
There is an import/export feature in the data factory canvas which supports this use case.
Moreover, this is the case where continuous deployment and integration proves very useful. More literature can be found - https://learn.microsoft.com/en-us/azure/data-factory/continuous-integration-deployment
Being novice to ADF CICD i am currently exploring how we can update the pipeline scoped parameters when we deploy the pipeline from one enviornment to another.
Here is the detailed scenario -
I have a simple ADF pipeline with a copy activity moving files from one blob container to another
Example - Below there is copy activity and pipeline has two parameters named :
1- SourceBlobContainer
2- SinkBlobContainer
with their default values.
Here is how the dataset is configured to consume these Pipeline scoped parameters.
Since this is development environment its OK with the default values. But the Test environment will have the containers present with altogether different name (like "TestSourceBlob" & "TestSinkBlob").
Having said that, when CICD will happen it should handle this via CICD process by updating the default values of these parameters.
When read the documents, no where i found to handle such use-case.
Here are some links which i referred -
http://datanrg.blogspot.com/2019/02/continuous-integration-and-delivery.html
https://learn.microsoft.com/en-us/azure/data-factory/continuous-integration-deployment
Thoughts on how to handle this will be much appreciated. :-)
There is another approach in opposite to ARM templates located in 'ADF_Publish' branch.
Many companies leverage that workaround and it works great.
I have spent several days and built a brand new PowerShell module to publish the whole Azure Data Factory code from your master branch or directly from your local machine. The module resolves all pains existed so far in any other solution, including:
replacing any property in JSON file (ADF object),
deploying objects in an appropriate order,
deployment part of objects,
deleting objects not existing in the source any longer,
stop/start triggers, etc.
The module is publicly available in PS Gallery: azure.datafactory.tools
Source code and full documentation are in GitHub here.
Let me know if you have any question or concerns.
There is a "new" way to do ci/cd for ADF that should handle this exact use case. What I typically do is add global parameters and then reference those everywhere (in your case from the pipeline parameters). Then in your build you can override the global parameters with the values that you want. Here are some links to references that I used to get this working.
The "new" ci/cd method following something like what is outlined here Azure Data Factory CI-CD made simple: Building and deploying ARM templates with Azure DevOps YAML Pipelines. If you have followed this, something like this should work in your yaml:
overrideParameters: '-dataFactory_properties_globalParameters_environment_value "new value here"'
Here is an article that goes into more detail on the overrideParameters: ADF Release - Set global params during deployment
Here is a reference on global parameters and how to get them exposed to your ci/cd pipeline: Global parameters in Azure Data Factory
How can I use a truncate command to truncate all the values inside multiple tables? And how to pass this inside the Copy Preview feature?
How to copy the latest blob to Azure datawarehouse using copy preview?
I have various tables in various folders with multiple amounts of data. How can I write JSON to only copy the latest data to Azure datawarehouse?
I don't feel like you've tried very hard here and are expecting free dev work.
The copy wizard in ADFv1 is only for a very specific purpose and isn't very good. You won't be able to use it for more complex things like you describe above.
I recommend you open up Visual Studio 2015, load an ADFv1 project and start figuring out what JSON you need.
There are plenty of resources out there to use to develop complex data factory pipelines.
You can achieve what you need by modifying the sqlReaderQuery property inside your pipeline. It was nicely explained here by g_brahimaj Execute storedProcedure from azure datafactory do the same, but change the exec command for the truncate command that you need.
