// We have indices on id, name, total credit, and RAC.
|
|
// So we provide the following searches:
|
|
// - new users in last N days (1, 7)
|
|
// - users with names starting with X
|
|
// - users ordered by decreasing total credit
|
|
// - users ordered by decreasing RAC
|
|
//
|
|
// In addition you can filter by:
|
|
// - a given country
|
|
// - with/without profile
|
|
// - with/without team
|
|
//
|
|
// We don't do the filtering in the SQL, because that would
|
|
// lead to table scans in the worst case.
|
|
// Instead we use the following policies:
|
|
// - a given search can scan no more than MAX_ROWS rows
|
|
// - a given search can return no more than MAX_RESULTS results
|
|
//
|
|
// here's how we do this:
|
|
// result_list = empty
|
|
// while n<MAX_ROWS
|
|
// enumerate rows w/o filtering, limit n, 1000
|
|
// (read only the fields we need for display)
|
|
// scan through batch, doing filtering, appending to result_list
