Copy Data Activity Failed with Unreasonable Cause
It is a simple set up but it has baffled me a lot. I'd like to copy data to a data lake via API. Here are the steps I've taken: Created a HTTP linked service as below: Created a dataset with a HTTP Binary data format as below: Created a pipeline with a Copy Data activity only as shown below: Made sure linked service and dataset all working fine as below: Created a Sink dataset with 3 parameters as shown below: Passed parameters from pipeline to Sink dataset as below: That's all. Simple, right? But the pipeline failed with a clear message "usually this is caused by invalid credentials." as below: Summary: No need to worry about the Sink side of parameters etc. which I have used same thing for years on other pipelines and all succeeded. This time the API failed to reach a data lake from source side as said "invalid credentials". In Step 4 above one could see the linked service and dataset connections were succeeded, ie. credentials have been checked and passed already. How come it failed in data copy activity complaining an invalid credentials? Pretty weird. Any advice and suggestions will be welcomed.
User Properties of Activities in ADF: How to add dynamic content in it?
On ADF, I am using a for each loop in which I am using an Execute Pipeline Activity which is getting executed for different iterations as per the values of the items provided to the For-Each Loop. I am stuck on a scenario which requires me to add the Dynamic Content Expression in the User Properties of individual activities of ADF. Specific to my case, I want to add the Dynamic Content Expression in the User Properties of Execute Pipeline Activity so that I get to individual runs of these activities on Azure Monitor with a specific label attached to it through its User Properties. The necessity to add the Dynamic Content Expression in the User Properties is due to the reason that each execution in respective iterations of these activities corresponds to a particular Step from a set of Steps configured for the Data Load Job as a whole, which has been orchestrated through ADF. To identify the association with the respective Job-Step, I require to add Dynamic Content Expression in its User Properties. Any sort of response regarding this is highly appreciated. Thank You!
Dataflow snowflake connection issue
I'm trying to set up a sink to snowflake in dataflow, but when I test the connection it doesn't work It just comes out JDBC driver communication error, tried searching online and looking at documentation link but couldn't find anything about this issue. But this same dataset works fine outside of the dataflow, I can preview the data in same dataset: There seems to be issue with dataflow. Even when I try to execute the dataflow through pipeline the same error message comes up: Does anyone know how to solve this problem with dataflows? Also with the sink settings option if I select recreate table will it create the table in snowflake if it doesn't already exist? Trying to find an easy way to copy a lot of tables into snowflake without explicitly having to create the table first especially if the metadata is only known at runtime, the pipeline copy job doesn't work as the table has to exist before it can insert data into it, but dataflow seems promising if the connection actually works.
Oracle 2.0 Upgrade Woes with Self-Hosted Integration Runtime
This past weekend my ADF instance finally got the prompt to upgrade linked services that use the Oracle 1.0 connector, so I thought, "no problem!" and got to work upgrading my self-hosted integration runtime to 5.50.9171.1 Most of my connection use service_name during authentication, so https://learn.microsoft.com/en-us/azure/data-factory/connector-oracle?tabs=data-factory, I should be able to connect using the Easy Connect (Plus) Naming convention. When I do, I encounter this error: Test connection operation failed. Failed to open the Oracle database connection. ORA-50201: Oracle Communication: Failed to connect to server or failed to parse connect string ORA-12650: No common encryption or data integrity algorithm https://docs.oracle.com/error-help/db/ora-12650/ I did some digging on this error code, and the troubleshooting doc suggests that I reach out to my Oracle DBA to update Oracle server settings. Which, I did, but I have zero confidence the DBA will take any action. https://learn.microsoft.com/en-us/azure/data-factory/connector-troubleshoot-oracle Then I happened across this documentation about the upgraded connector. https://learn.microsoft.com/en-us/azure/data-factory/connector-oracle?tabs=data-factory#upgrade-the-oracle-connector Is this for real? ADF won't be able to connect to old versions of Oracle? If so I'm effed because my company is so so legacy and all of our Oracle servers at 11g. I also tried adding additional connection properties in my linked service connection like this, but I have honestly no idea what I'm doing: Encryption client: accepted Encryption types client: AES128, AES192, AES256, 3DES112, 3DES168 Crypto checksum client: accepted Crypto checksum types client: SHA1, SHA256, SHA384, SHA512 But no matter what, the issue persists. :( Am I missing something stupid? Are there ways to handle the encryption type mismatch client-side from the VM that runs the self-hosted integration runtime? I would hate to be in the business of managing an Oracle environment and tsanames.ora files, but I also don't want to re-engineer almost 100 pipelines because of a connector incompatability.Prevent Accidental Deletion of an Instance in Azure Postgres

Increasing the number of scripts for Bicep deployments
We were quite surprised to run into a limit of 50 scripts per ADX cluster limit... Considering there is a limit of 10,000 databases, having a limit of 50 scripts seems wrong... Is this a bug? Anyway to increase it? Our use-case would really require that we can provision certain assets alongside our Bicep infra code. We give each customer their own database and provision certain defaults tables and table mapping assets there. We started to hit this 50 script limits just after 4 customers...Data flow sink to Blob storage not writing to subfolder
Hi Everybody This seems like it should be straightforward, but it just doesn't seem to work... I have a file containing JSON data, one document per line, with many different types of data. Each type is identified by a field named "OBJ", which tells me what kind of data it contains. I want to split this file into separate files in Blob storage for each object type prior to doing some downstream processing. So, I have a very simple data flow - a source which loads the whole file, and a sink which writes the data back to separate files. In the sink settings, I've set the "File name option" setting to "Name file as column data" and selected my OBJ column for the "Column Data", and this basically works - it writes out a separate file for each OBJ value, containing the right data. So far, so good. However, what doesn't seem to work is the very simplest thing - I want to write the output files to a folder in my Blob storage container, but the sink seems to completely ignore the "Folder path" setting and just writes them into the root of the container. I can write my output files to a different container, but not to a subfolder inside the same container. It even creates the folder if it's not there already, but doesn't use it. Am I missing something obvious, or does the "Folder path" setting just not work when naming files from column data? Is there a way around this?September 2025 Recap: What’s New with Azure Database for PostgreSQL

Problem with Linked Service to SQL Managed Instance
Hi I'm trying to create a linked Service to a SQL Managed Instance. The Managed Instance is configured with a Vnet_local endpoint If I try to connect with an autoresolve IR or a SHIR I get the following error The value of the property '' is invalid: 'The remote name could not be resolved: 'SQL01.public.ec9fbc2870dd.database.windows.net''. The remote name could not be resolved: 'SQL01.public.ec9fbc2870dd.database.windows.net' Is there a way to connect to it without resorting to a private endpoint? Cheers AlexAzure SQL server rollback itself?
We have an Azure SQL server. It is a datasource of a Power App canvas app. Today I connected to it with SSMS v19. First, I ran 'Begin tran' twice (is it a mistake?). Then 'Delete From dbo.table1 where ID=30' and another row with ID=31. Then I verified these 2 rows are deleted by 'Select * from dbo.table1' Finally, I ran 'Commit tran' I verified again above 2 rows are deleted by 'Select * from dbo.table1' However, there is no change in the Power App. So I reopen the SSMS and connect to the DB again. This time when I ran 'Select * from dbo.table1', the 2 rows are showing up. What could be the problem? Is it a bug in old version SSMS?

Hello, everyone! I have a complex question about how to perform a partial update on a MongoDB collection using Data Flow in Azure Data Factory. My goal is to modify only some nested fields without overwriting the entire document. My flow reads JSON files with the following structure: { "_id": { "$oid": "1xp3232to" }, "root_field": "root_value", "main_array": [ { "array_id": "id001", "status": "PENDING", "nested_array": [] } ], "numeric_value": { "$numberDecimal": "10.99" } } I need Data Flow to make two changes in a single run: Change the status field from "PENDING" to "SENT". Add a new object to the nested_array with the following data: event: "SENT" description: "FILE GENERATED" timestamp: (current date and time) system: "Sis Test" I've tried some expressions with update and append in the Derived Column transformation, but I can't get the syntax right to make both changes at the same time. My biggest concern is with the MongoDB Sink: how to configure it so that Data Flow performs a partial update and doesn't overwrite the entire document, losing root_field, numeric_value, etc.? My questions are: What is the correct expression for the Derived Column that makes these two nested modifications in a single step? How should I configure the MongoDB Sink to ensure the update is partial, using _id as the key? I really appreciate the community's help!

I enabled query acceleration for my external table which binds a delta table (1TB) on ADLS. But acceleration progress needs 1.5 hours to complete. I found during acceleration in progress, querying on the table is quite slower than case when acceleration completed. How can I use the existing acceleration cache/index and after acceleration completed, Kusto will switch to new index?
