Problem with large data

[rentehaee]

Hi everyone
I implemented a Reconciliation-csv server for a local data set where the file has an id column and a data column. This file has 752982 records. When I select CSV reconciliation Service I get this message:

"Guess Types query failed error : java.net.SocketTimeoutException: Read timed out"

But, When I decreased the number of records in the csv file to 400,000, the problem was solved. But I need to do the matching with the total number of records.
Is there a solution to this problem?
