ios - How to load thousands records to Realm correctly? -


i'm trying save 8000 records disk, using realm, it's blocking ui. result, use realm.asyncopen performs data saving in background thread.

the problem 100% cpu usage when try save big amount of records manner.

how load thousands records realm correctly?

try way in official demo save large amounts of data:

dispatchqueue(label: "background").async {   autoreleasepool {     // realm , table instances thread     let realm = try! realm()      // break writing blocks smaller portions     // starting new transaction     idx1 in 0..<1000 {       realm.beginwrite()        // add row via dictionary. property order ignored.       idx2 in 0..<1000 {         realm.create(person.self, value: [           "name": "\(idx1)",           "birthdate": date(timeintervalsince1970: timeinterval(idx2))         ])       }        // commit write transaction       // make data available other threads       try! realm.commitwrite()     }   } }

recursion - Can every recursive algorithm be improved with dynamic programming? -

i first year undergraduate csc student looking competitive programming. recursion involves defining , solving sub problems. understand, top down dynamic programming (dp) involves memoizing solutions sub problems reduce time complexity of algorithm. can top down dp used improve efficiency of every recursive algorithm overlapping sub problems? dp fail work , how can identify this? the short answer is: yes. however, there constraints. obvious 1 recursive calls must overlap. i.e. during execution of algorithm, recursive function must called multiple times same parameters. lets truncate recursion tree memoization. can use memoization reduce number of calls. however, reduction of calls comes price. need store results somewhere. next obvious constraint need have enough memory. comes not-so obvious constraint. memory access requires time. first need find result stored , maybe copy location. in cases, might faster let recursion calculate result instead of loading somewher...
