15 TopicsFabric compute capacity exceeded its limits. How to know how much CU each dataflowgen2 consumes
Our dataflowgen2 got Failed status after exceeding the Fabric compute capacity limit At the moment, I'm trying to access Fabric Capacity Metrics to see if it can be viewed there but cant open it as well with message "Unable to load model due to reaching capacity limits" - How to know how much CU each activity(dataflowgen2,notebook,etc) in a datapipeline consume so we can avoid hitting the CU limit? - Do we have other way to view fabric capacity metrics?Solved21KViews0likes7CommentsLackluster Data Warehouse performance
I am writing this because I am getting fed up with the ill performance of Datawarehouse. Here is my current setup: (External Data such as SQL, Sharepoint, and GA4) => (Dataflow Gen2) => (Data WareHouse) => (Dataset) => (Report) The issue lies with the data warehouse, it is without fail that once or twice a week I have to manually go and click the refresh button on my Dataset that points at the data warehouse because the connection to the warehouse failed or timed out. A simple click of the refresh and it's fine. That would be find except now, the performance on the warehouse just tanked. Now when I try to do a simple select top 1 (seq_no) from Table I tried to let it load for over 30 minutes and no results. I have lost all faith in data warehouses. I have also set up a data lake house in a different workspace and different project. This one is connected to a gen 2, and similar issues in the fact that without fail 1 or 2 times a week I have to go in and click the refresh button on the data set because it is unable to establish connection to the lake house. It works fine after that. For reference: Gateway is (3000.214.8) ( I know there is a new version, waiting on our network teams schedule to have it pushed, but this issue existed prior to the new release) Let me know if you need anymore details or if i should just open a ticket.Solved1.8KViews0likes3CommentsHow to Integrate Data from High-Speed Manufacturing Line into Microsoft Fabric
Hello, I need assistance with integrating data from our high-speed manufacturing line into Microsoft Fabric. Here are the specifics: Setup: High-speed manufacturing line using an industrial communication protocol (e.g., Profibus, Modbus, Ethernet/IP, PROFINET, or OPC UA). Goal: To extract data from this setup and load it into Microsoft Fabric services for further processing and analysis. Challenges: Understanding the best approach and tools to use for this integration, including any middleware required. Could anyone provide guidance or share experiences on: The best middleware or connectors for interfacing common industrial protocols with Microsoft Fabric services. Steps or best practices for setting up this integration. Any potential pitfalls to be aware of. Thank you!2.4KViews0likes9CommentsCSV file to DataLake Table not converting properly
Hi All I have uploded a CSV file into a DataLake and created a table from it, but table columns values coming up differently from csv values: CSV: Site,FileUrl,Size,Created,Modified,Name,Author,Editor SiteName1 , /sites/SiteName1/Shared Documents/Barclays/Contracts/BarclaysContract 2013.pdf , 2.48953819274902 , 08/11/2015 09:41:20 , 08/11/2015 09:41:20 , BarclaysContract 2013.pdf , , SiteName1 , /sites/SiteName1/Shared Documents/Barclays/Contracts/Barclays Client Contract.pdf , 3.56038379669189 , 08/11/2015 09:41:13 , 08/11/2015 09:41:13 , Barclays Client Contract.pdf , , DataLake table: I know some file may contain commas and that could be cosing this issue, but majority are ok Is there any way to sort it? Thanks1.2KViews0likes3CommentsConnect to Lakehouse without MFA
HI Guys, I have a need to connect BrightGauge to Microsoft Lakehouse as an SQL connection. The problem is that BrightGauge cannot handle the modern authentication. Has anyone had luck connecting to a Lakehouse using legacy authentication database username and password?Solved2.1KViews0likes5CommentsWhy lakehouses are not independent one of each other when Git is integrated?
Hi, I have integrated Git to a workspace and I have feature branch, development and main branch. If I'm on feature branch and if I make changes to the lakehouse using fabric notebooks the lakehouse will also be changed on development and main branch, why? Shouldn't lakehouses (delta parquet files) be independent one of each other according to the branches? Regards, Igor888Views0likes3CommentsSELECT COUNT only gives 1000 in lakehouse query
Hi All May not be the right forum, but I couldnt find Lakehouse one so posting it here I have a Dataflow gen2 that adds few thousands rows to a datalake table everyday, and I tried to check he total quantity of rows with SELECT COUNT(*) sql query but it only shows 1000 rows 😞 Any idea how to remove that 1000 limit? Thanks1.5KViews0likes4CommentsLakehouse Add or Remove columns from table
Not sure if this is the right forum or not - but here is the issue. We are loading data to a Lakehouse using gen 2 data flows (for now they are just pointing at exisitn gen 1 dataflows then doing the lakehouse insert - we will recify this later on). Over time it is typical for columns to be added, removed and / or updated in a dataflow - with a datamart these changes are reflected automatically in the schema - however with a laehouse when adding a new column to the dtaflow i can see no way to bring that into the lakehouse. What do i need to do here - only options i can see are 1: import it as a new table but that seems to be very clunky as you would need to update queoroes / stored procedures on your sql end point to cater for this 2: Delete exisitng table in lakehouse and then add a new one with the same name. Am i missing something ?26KViews7likes10CommentsSparkR save to table question
I'm sure this is basic, but I've tried googling etc and Im lost: My go-to programming language is R and I'd love to begin using R in Spark R notebooks and spark job definitions. So far I've written some R code in a notebook that: -loads some packages (had to figure out how to pre-install them in a custom environment) -connects to a redcap database via api -grabs some data from that database -saves it as a csv in a lakehouse in the "files" Manually (not with R), I've clicked the csv to "load to tables" and made it a table I then connected a power bi dashboard to it. Thats great, but really what I'd like to do is incorporate this R script into a dataflow that saves the data directly into a table (so i dont have to do that clicking). Am I understanding correctly that "tables" in Fabric are "parquet" tables? And if so, can they be saved directly? My R code looks roughly like this: dataFromRedcap<-redcap_read(redcap_uri = url,token = token) data2<-dataFromRedcap$data From there, I've saved it to csv with temp_csv_api <- "/lakehouse/default/Files/redcap.csv" readr::write_csv(data2,temp_csv_api) but is there a comparable step I could do that would save it to tables?Solved3KViews0likes3CommentsFull list of IP addresses for *.datawarehouse.pbidedicated.windows.net
Hi - we're trying to get our on-premise gateway to properly work with Fabric lakehouse and warehouse destinations. According to the docs we need to add firewall rules to allow access for port 1433 (TDS endpoint) to *.datawarehouse.pbidedicated.windows.net. Unfortunately, it seems like our software is older and we need to add individual IP addresses instead of a wildcarded URL. Is there anywhere that a FULL list of IP addresses is kept? My Gen2 dataflows are for the most part working - but still fail intermittently with what seems to be networking type errors. I'm concerned that while testing we didn't get a full list of IPs.
