QUESTION
I am using a Python POST request to geocode the addresses of my company's branches, but I'm getting wildly inaccurate results.
I looked at this answer, but the problem is that some results aren't being processed. My problem is different in that all of my results are inaccurate, even ones with Confidence="High". And I do have an enterprise account.
Here's the documentation that shows how to create a geocode Job and upload data:
https://docs.microsoft.com/en-us/bingmaps/spatial-data-services/geocode-dataflow-api/create-a-geocode-job-and-upload-data
here's a basic version of my code to upload:
...ANSWER
Answered 2021-Jun-02 at 15:28I see several issues in your request data:
- The "query" value you are passing in is a combination of a point of interest name and a location. Geocoders only work with addresses. So in this case the point of interest name is being dropped and only "Los Angeles" is being used by the geocoder, thus the result.
- You are mixing two different geocode query types into a single query. Either use just "query" or just the individual address parts (AddressLine, Locality, AdminDistrict, CountryRegion, PostalCode). In this case, the "query" value is being used an everything else in being ignored, using the individual address parts will be much more accurate than your query.
- You are passing in the full address into the AddressLine field. That should only be the street address (i.e. "8830 Slauson Ave").
Here is a modified version of the request that will likely return the information you are expecting:
QUESTION
The "pandasdmx" documentation has an example of how to set dimensions, but no how to set attributes. I tried passing "key" to the variable, but an error occurs. Perhaps setting attributes requires a different syntax? At the end of my sample code, I printed out a list of dimensions and attributes.
...ANSWER
Answered 2021-May-29 at 10:47To clarify, what you're asking here is not “how to set attributes” but “how to include attributes when converting (or ‘writing’) an SDMX DataSet to a pandas DataFrame”.
Using sdmx1,¹ see the documentation for the attribute parameter to the write_dataset() function. This is the function that is ultimately called by to_pandas() when you pass a DataSet object as the first argument.
In your sample code, the key line is:
QUESTION
I have a pair of target tables which have a foreign key realtionship. The primary key of the parent table is generated by a database sequence on insert so the insert into the child table has to be performed after the parent's primary key has been generated.
I want to insert a pair of records into the tables as a single transaction in Azure Data Factory.
Is it possible, in a single DataFlow, to insert into the parent table, and then insert into the child using a value from the newly inserted record? I have a legacy key value in the parent that I can use to identify the newly generated primary key.
In SQL terms, the insert into the child would look like this:
...ANSWER
Answered 2021-May-05 at 08:14I'm pretty sure the answer to this is "No you can't, not just with ADF anyway".
What we would need to do to work around this is to build something in the database, such as a view with an on-insert trigger that looks up the foreign key and substitutes the value.
QUESTION
Update: Microsoft have identified the problem and will be fixing it!
I am attempting to use Azure Data Factory to load a parent and child table in Azure SQL, which is enforced in the database by a foreign key.
My DataFlow is very simple, reading from staging tables and writing 1-for-1 into the destination tables. One of the reads has an exists constraint against a third table to ensure that only the correct subset of records are loaded.
I have two very similar DataFlows loading two kinds of record with similar parent-child relationships, one of them works just fine, the other fails with a foreign key violation. Sometimes. It's not consistent, and changing seemingly unrelated things such as refreshing a Dataset schema sometimes makes it work.
Both DataFlows have Custom Sink Ordering set to make the parent table insert happen first at Order 1, and the child record happen at Order 2.
Am I using this feature correctly, is this something that Custom Sink Ordering should give me?
This is the job layout, it's actually loading two child tables:
I tried removing the top sink, so it only loads the Write Order 1 table (sinkSSUSpatialUnit) and the Write Order 2 table (sinkSSUCompartment) that is failing with a foreign key violation, and the problem does not happen in that cut-down clone of the DataFlow.
Microsoft have found a problem with Custom Sink Order not working as intended intermittently, and will be fixing it. I will update this if I find out any more.
...ANSWER
Answered 2021-Mar-26 at 07:44In the documentation, MS does not say anything about the order of the source: https://docs.microsoft.com/en-us/azure/data-factory/data-flow-sink#custom-sink-ordering
Maybe yo can try to use the read committed isolation level for the source in order to see if ADF decides to wait to the sink before reading the source dataset.

QUESTION
We need to move users from an on-premise Active Directory on Windows Server (not Azure Active Directory) to Azure AD B2C. But, we're having difficulty in trying to figure out how to read the user data from the AD using Azure products.
We're thinking about using one of the following Azure products to read from on-premise AD, but it's surprisingly difficult to find if this is possible or not, much less how to do it:
- Azure Data Factory
- Azure Logic App
- Microsoft Power Platform Dataverse (formerly Common Data Service)
- Power BI Data Flows
- Note: We can't use Azure AD Connect to migrate the users because that tool isn't designed to work with B2C. Reference Microsoft's Azure AD B2C: Frequently asked questions (FAQ).
The Microsoft article Migrate users to Azure AD B2C says that a script needs to be written that uses the Microsoft Graph API to create user accounts in Azure AD B2C. But the article doesn't give advice on how to access the source data, which in our case is AD.
...ANSWER
Answered 2021-Feb-02 at 02:15There is no out-of-box Azure product/solution that connects to on-prem AD. Maybe there is a way which requires you create custom connector and custom API for querying AD users. See this post.
The quickest way is using PowerShell cmdlet Get-ADUser to export the AD users and then import them into Azure B2C via Microsoft Graph Create User.
QUESTION
I've debugged my ADF pipeline, The pipeline contains 4 copy activities and two DataFlows. After the Debug is done , I switched to Azure Purview to look at the changes done to the Datafactory and I was able to see the Pipeline. But when I go into the pipeline in Azure Purview all the activities and the Dataflows appear with lineage except one Dataflow. This Dataflow sinks into an SQL table that doesn't exist , so it auto creates the Table. Is this the reason why it isn't appearing in the purview??
...ANSWER
Answered 2020-Dec-15 at 04:02At this time, lineage into auto-created tables from a data flow is not a supported scenario. This is on the Azure Purview roadmap, but unfortunately we do not have an ETA right now.

I am doing a truncate and Load of a delta File in ADLS Gen2 using Dataflows in ADF. After the successful run of Pipeline if I am trying to read the file in Azure Data Bricks i am Getting the below error.
A file referenced in the transaction log cannot be found. This occurs when data has been manually deleted from the file system rather than using the table DELETE statement. For more information,
One way which I found to eliminate this is restart the cluster in ADB. But, is there a better way to overcome this issue?
...ANSWER
Answered 2020-Nov-17 at 12:48Sometimes changes in table partitions/columns will not be picked by hive megastore, refresh the table is always a good practice before you trying to do some queries. This exception can occur if the metadata picked up from the current job is altered from any other job while this job still running.
Refresh Table: Invalidates the cached entries, which include data and metadata of the given table or view. The invalidated cache is populated in a lazy manner when the cached table or the query associated with it is executed again.
QUESTION
I'm using Power BI Dataflows to access spreadsheets I have in blob storage. I have configured IAM permissions on the storage account for myself and the Power BI Service user. The network configuration is set to 'Allow trusted Microsoft services to access this storage account' and 'Microsoft network routing endpoint' preferences.
First Test: Storage Account allowing access from all networks
I am able to access the spreadsheet from the Power BI Service and perform transformations.
Second Test: Storage Account allowing only selected networks
In this case, I have added a group of CIDR blocks for other services that need to access the storage account. I have also added the whitelists for the Power BI Service and PowerQueryOnline service using both the deprecated list and new json list.
When running the same connection from Power BI Service Dataflows I now get the 'Invalid Credentials' error message. After turning on logging for the storage account and running another successful test it looks like the requests are coming from private IP addresses (10.0.1.6), not any of the public ranges.
...ANSWER
Answered 2020-Sep-18 at 15:30Have you tried to enable a Service endpoint for Azure Storage within the VNet? The service endpoint routes traffic from the VNet through an optimal path to the Azure Storage service.
Could you also check if you have whitelisted the following links, you will find them in this link:

QUESTION
I have a requirement to trigger the Cloud Dataflow pipeline from Cloud Functions. But the Cloud function must be written in Java. So the Trigger for Cloud Function is Google Cloud Storage's Finalise/Create Event, i.e., when a file is uploaded in a GCS bucket, the Cloud Function must trigger the Cloud dataflow.
When I create a dataflow pipeline (batch) and I execute the pipeline, it creates a Dataflow pipeline template and creates a Dataflow job.
But when I create a cloud function in Java, and a file is uploaded, the status just says "ok", but it does not trigger the dataflow pipeline.
