Kevin Chant digs into Azure Synapse Link for SQL Server 2022:
In this post I want to cover some file tests for Azure Synapse Link for SQL Server 2022 that I performed.
Because a while back I spotted something interesting whilst I was doing some initial tests for Azure Synapse Link for SQL Server 2022.
Which is when you add new data after the initial load that a new folder called ‘ChangeData’ appears in the storage account container. I noticed that the new file containing the insert was a comma separated value (csv) file. Whereas the table used for the initial load was a parquet file.
Is there a method to this madness? Click through to see Kevin’s tell-all story.
