I am thinking through a problem, if I get a table, and the data in it keep growing, thousand, million, billion ….
One day, I think even a simple query it will need several seconds to run.
So is there any means which we can use to control the time within 1 second or any reasonable time ?
Partitioning. The fastest I/O’s you can do are the one you don’t need to do.
Indexing. As appropriate, not for every column. You can’t make every query run at memory speed, so you have to pick and choose.
Realism. You’re not processing a billion I/Os through a relational engine in a single second.
