 db = conn1["ASSET_TRACKING"];

     if (k != -1)
                {
                 // qDebug() << "value found at "<<k ;

                  {
                     std::vector<bsoncxx::document::value> documents;
                     documents.push_back(
                     bsoncxx::builder::stream::document{} <<"tag_ID"<< e.toStdString() <<"POSX"<<posx<<"POSY"<<posy<<"POSZ"<<posz<< finalize);
                     db["Tagdemo"].insert_many(documents);

// if(posx<30 &&posy<30)
// {
// db["Tag1"].update_one(bsoncxx::builder::stream::document{} <<"bool"<< 1 << finalize,
// bsoncxx::builder::stream::document{} << "$set" << open_document <<
// "tag_ID"<< e.toStdString() <<"POSX"<<posx<<"POSY"<<posy<<"POSZ"<<posz << close_document << finalize);
//
// }
}

code part

What code is that?
What is db?
Do you do it in a loop?
Please explain better!

@jsulm Ok, iam using qtcreator 5, Database mongodb .
above code is placed inside a loop ,loop works when there is data available in socket .Data reads fast from socket, when i put mongodb insertion code here it makes application not responding ,,
can we call mongodb insertion faster??
is that code logic problem or need to do it in thread??

@Vivek_A I also asked what "db" is in your code. Can you please answer?

Vivek_A

@jsulm db i updated above

@Vivek_A You are asking about mongocxx::database which has nothing to do with Qt!
Are you doing these inserts in main (GUI) thread? If so move this code into a second thread to not to block your main thread.

@Vivek_A
I note that all your questions are about mongodb, its performance, and so on. Have you tried joining some mongodb forum where these might be better answered?
