Today, we had a very interesting service request that our customer requested to improve the process for inserting 10 millions of rows.
In this type of situation, we need to think about the the time spent in networking roundtrips.
In order to explain this I developed three different Powershell Scripts that you could find out in this GitHub repository
- InsertThis, basically is a Powershell command to insert the data and measure the time inserting every single row, using an INSERT command.
- InsertStore, basically is a Powershell command to insert the data and measure the time inserting every row, calling a parametrized query to reduce the amount of bytes sending to database.
- InsertBulk, basically is a Powershell command to insert the data using batches and BulkCopy technology.
In all the tests done, InsertBulk was the process that much faster inserted the data.
