It entirely depends on your query. If you are just finding by ID, then it's likely to be in the 7 figure range (10,000,000+).
If you're doing complex joins and searches within strings, then you'd need to test it. The short answer is test it! It's easy enough in script/console to quickly insert a million rows, then actually test/benchmark your app. Cheers, Andy -- Andy Jeffries http://andyjeffries.co.uk/ #rubyonrails #mysql #jquery Registered address: 64 Sish Lane, Stevenage, Herts, SG1 3LS Company number: 5452840 On 29 April 2010 09:13, TechSlam <aslam9...@gmail.com> wrote: > Hi > > I have a Student table with 30 columns in it. > > My question is at what database size, would the query performance be > affected? > > We are actually planning to have a ArchivedStudent table(which has > exactly the same structure as that of Student table) so that when > student graduates, his record can be moved out of active Student table > to ArchivedStudent table. or should I just go for named scopes? > > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to rubyonrails-t...@googlegroups.com. > To unsubscribe from this group, send email to > rubyonrails-talk+unsubscr...@googlegroups.com<rubyonrails-talk%2bunsubscr...@googlegroups.com> > . > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
