Azure数据工厂 - 从MySql或Blob存储中提取数据时出错

Question

Since last week we're facing some issues involving Data Factory Copy Activities. The issue occurs when the data is already staged into the Blob Storage and it starts to be copied into the SQL DW.

What we can see is that the Throughput rate decreases till we get the following message error:

{ "errorCode": "2200", "message": "ErrorCode=UserErrorFailedToConnectToSqlServer,'Type=Microsoft.DataTransfer.Common.Shared.HybridDeliveryException,Message=Cannot connect to SQL Server: 'despesas.database.windows.net', Database: 'csc', User: 'master'.,Source=Microsoft.DataTransfer.ClientLibrary,''Type=System.Data.SqlClient.SqlException,Message=A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.),Source=.Net SqlClient Data Provider,SqlErrorNumber=121,Class=20,ErrorCode=-2146232060,State=0,Errors=[{Class=20,Number=121,State=0,Message=A connection was successfully established with the server, but then an error occurred during the pre-login handshake. (provider: TCP Provider, error: 0 - The semaphore timeout period has expired.),},],''Type=System.ComponentModel.Win32Exception,Message=The semaphore timeout period has expired,Source=,'", "failureType ": "UserError", "target": "Copy Data1"

Notice that the issue started last week!

Answer 1

Try creating an Azure Integration Runtime in the same region of the SQL database, sometimes the auto detect region doesnt work.

Create an Azure IR in that region, and create the linked service again, using the new Integration Runtime.

That should solve your problem.

Hope this helped!
