Query folding with ODBC Redshift Connection?

[mf2499pbi]

Hi all,

I am connecting to AWS Redshift using an ODBC connection. It seems as if Query Folding should be available while connecting this way, but it is not working for me. 

When I filter the top 100 rows and load the data, it goes through millions of rows before finishing the load. Is there anything I can do to enable query folding? I have tried the Value.NativeQuery function, but this does not work with ODBC.

Hi @mf2499pbi 

According to article Import data from a database using native database query - Power Query, query folding while using a native database query is limited to only a certain number of Power Query connectors. Below are the supported data connectors. ODBC is not listed among them. For more information, go to Query folding on native queries.

As Amazon Redshift connector is available and supports query folding using a native query, you may use this connector instead to have a try.
