Low I/O performance during reading a big table
Hello for all! I have a large database - more than 2 Tb. These database has two large tables of over than 400 Gb each. I need to export these tables to file for external processing by my partner....
It must read all the rows in the table.
And "read" means what in detail? If you are using a tool like SSMS, the it already needs a lot of time to shoe the data.
