I'm new to Azure synapse Analytics. I'm trying to copy data from my mongodb Atlas cluster to a datalake
I'm trying to use a private endpoint to authorize the connection from my Azure Synapse workspace, but I always get a timeout issue every time I try to test the connection from the service linked MongoDb. Any ideas on how to get my MongoDB Atlas databases to communicate with Azure Synapse Analytics without allowing all IP addresses? Thanks

I am using the following link to guide me on connecting Tableau to ADLS Gen2 https://help.tableau.com/current/pro/desktop/en-us/examples_azure_data_lake_gen2.htm
I have got stuck at the first hurdle where the document states
Start Tableau and under Connect, select Azure Data Lake Storage Gen2.
For a complete list of data connections, select More under To a
Server.
I don't have that option with the version of Tableau I just downloaded.
Should I be downloading a different version of Tableau to see the option to select Azure Data Lake Storage Gen2?
You're using Tableau Public (limited connection options), but if you download Tableau Desktop (even on a 14day trial) it will work
What is the best method to sync medical images between my client PCs and my Azure Blob storage through a cloud-based web application? I tried to use MS Azure Blob SDK v18, but it is not that fast. I'm looking for something like dropbox, fast, resumable and efficient parallel uploading.
Solution 1:
AzCopy is a command-line tool for copying data to or from Azure Blob storage, Azure Files, and Azure Table storage, by using simple commands. The commands are designed for optimal performance. Using AzCopy, you can either copy data between a file system and a storage account, or between storage accounts. AzCopy may be used to copy data from local (on-premises) data to a storage account.
And also You can create a scheduled task or cron job that runs an AzCopy command script. The script identifies and uploads new on-premises data to cloud storage at a specific time interval.

Solution 2:
Azure Data Factory is a fully managed, cloud-based, data-integration ETL service that automates the movement and transformation of data.
By using Azure Data Factory, you can create data-driven workflows to move data between on-premises and cloud data stores. And you can process and transform data with Data Flows. ADF also supports external compute engines for hand-coded transformations by using compute services such as Azure HDInsight, Azure Databricks, and the SQL Server Integration Services (SSIS) integration runtime.
Create an Azure Data Factory pipeline to transfer files between an on-premises machine and Azure Blob Storage.

Since I've starting using Azure Synapse Analytics, I created a Spark Pool Cluster, then on the Spark Pool cluster I created databases and tables using Pyspark on top of parquet files in Azure Data Lake Store Gen2.
I use to be able to access my spark Database/ parquet tables through SSMS using the Serverless SQL endpoint but now I can no longer see my spark Databases through the Severless SQL Endpoint in SSMS. My spark databases are still accessible through Azure Data Studio but not through SSMS. Nothing has been deployed or alter on my side. Can you help resolve the issue? I would like to be able to access my spark databases through SSMS.
Sql Serverless Endpoint
Azure Synapse Database
If your Spark DB is built on top of Parquet files, as you said, databases should sync to external tables in Serverless SQL pool just fine and you should be able to see synced SQL external tables in SSMS as well. Check this link for more info about metadata synchronization.
If everything mentioned above is checked, then I'd suggest you to navigate to Help + Support in Azure Portal and fill in a support ticket request with details of your problem so engineering team can take a look and see whether there is some issue with your workspace or not.

One solution is to use Azure Data Factory for data movement.
There's no built-in connector for Azure Analysis Service in Data Factory. But since Azure Analysis Services uses Azure Blob Storage to persist storage, you can use the connector for Azure Blob Storage.
In Data Factory, use a Copy Activity with Blob Storage as source and Azure Synapse Analytics as sink.

I am setting up a new Azure Data Lake Analytics (ADLA) PAAS service to run USQL against some existing data sets in blob storage. The blob storage is firewalled for security and when I try to add the storage account to the data sources in ADLA I get the following error. Similar happens for data factory.
InvalidArgument: The Storage account '' or its accessKey
is invalid.
If I disable the firewall, the storage account can be successfully added. I have tried to add the relevant Azure Data Center IP Address ranges but the connection still fails. I have also ticked the "Allow trusted Microsoft Services box" but this does not seem include data lake or data factory. How do I access my storage account from ADLA but still have it secured?
You could install a selfhosted IR to access your blob storage. Whitelist the IP of the machine hosting your selfhosted IR.
