I have a huge table, which has 3 columns and about 333,000 rows. The sql dump is about 58 MB, and the sqlite DB containing this one table is about 20 MB.

I want to implement a sort of “autocomplete” where the user types into a UISearchBar and a UITableView gets updated. I have it working where every time the user types a letter it makes an HTTPrequest, but there’s a very noticeable lag between the time the user types a letter and the UITableView gets updated. I was thinking storing the DB locally would speed things up, but, it’s a very large DB.

Is it feasible to store that large of a DB on a device? Would using Core Data be a better option?

    CoreData will end up using sqlite, so if you manage your memory correctly, and depending on how many records you handle at 1 time, you should be Ok.
