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...840Views0likes2CommentsData 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?11Views0likes0CommentsSeptember 2025 Recap: What’s New with Azure Database for PostgreSQL

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?

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?28Views0likes0CommentsADF connection issue with Cassandra

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!109Views0likes1CommentReliable Interactive Resources for Dp300 exam

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?120Views1like1CommentGetting an Oauth2 API access token using client_id and client_secret - help
Hi, I'm attempting to integrate external data into our SQL Server. The third-party data is from a solution called iLevel. They use token based Oauth2 APIs for access. The integration tool is ADF Pipelines. I'm not a data engineer but it has fallen upon me to complete this exercise. What I've attempted so far is failing and I don't know why. I would like your help on this. I'll explain what I've configured so far in the order I configured it. 1) To generate a client_id and client_secret, I logged on to the iLevel solution itself and generated the same for my account (call me 'Joe' account) and the Team account (call it 'Data team' account). I've recorded the client_id and client_secret for both users/accounts in notepad for reference. 2) I logged in Azure Data Factory using my 'Joe Admin' admin account (this is the account I need to log in with for any ADF development). 3) I created a Linked Service with the following configuration. Note how the Test connection was successful. I guess this means our ADF instance can connect to iLevel's Base URL. 4) I then created a dataset for iLevel. I configured this based on an online example I was following which I can't get working, so this configuration may be incorrect. 5) I then created a Pipeline which contains a 'Web' activity and a 'Set variable' activity. The Pipeline has a variable as shown below. The 'Web' activity has the following configuration: URL = is iLevel's token URL (it is different from the Base URL used in the Linked Service). Body = I've blocked out the client_id and client_secret (I'm using the client_id and client_secret generated for the 'Data team' account - remember I'm logged into ADF using the 'Joe Admin' account - not sure if this makes a difference) but have placed red brackets around where the start and end of each values is. I'm wrapping the values in any single or double quotes - not sure if I'm meant to. I'm not sure if I have configured the Body correctly. The ilevel documentation states to use an Authorization header, Content-Type header and Body - it states to the following is needed to obtain an access token, but it doesn't state exactly how to submit the information (i.e. how to format it). Notice how, in my configuration, I haven't used an Authorization header - this partly because an online example I've followed doesn't use one. If iLevel state to use one then I think I should but I don't know how to format it - any ideas? The 'Set variable' activity has the following activity. The idea is the access token is retrieved from the 'Web' activity and placed in the 'Set variable' "iLevel access token" variable. At this point I validate all and it comes back with no errors found. I then Debug it to see if it does indeed work but it returns an error stating the request contains an invalid client_id or client_secret. The client_id and client_secret values used are the exact same I generated from within the iLevel solution just a few hours ago. Is anyone able to point out to me why this isn't working? Have I populated all that I need to (as mentioned, iLevel say to use an Authorization header which I haven't but I don't know how to format it if I were to use one)? What can I do to get this working? I'm just trying to get the access token at the moment. I've not even attempted to extract the iLevel data and can't until I get a working token. iLevel's token have a 1 hour time-to-live so the Pipeline needs to generate a new token each time it's executed. You help will be most appreciated. Thanks.80Views1like0CommentsBest practice to integrate to Azure DevOps?
Different sources suggesting different recommendations regarding ADF and ADO integration. Some say to use 'adf_publish' branch, while some suggest to use 'main' branch to be source for triggering yaml pipelines and disabling 'Publish' function in ADF. I guess practices are changing and setup could be different. The problem is finding all this information on the Internet makes it so confusing. So, the question is what is the best practice now (taking into account all the latest changes in ADO) regarding branches? How you set up your ADF and ADO integrations?219Views1like3CommentsJuly 2025 Recap: Azure Database for PostgreSQL
