iOS: Object Pinning takes too much time

[Mohd-Aamir-M]

Below is the simple code i have, after few hundreds of pinned objects, new object take more than 12 seconds to pin.

-(void)saveToparse{
PFQuery query= [PFQuery queryWithClassName:@"register"];
[query fromPinWithName:self.registerId];
[query findObjectsInBackgroundWithBlock:^(NSArray *objects, NSError *error) {
if (objects.count==1) {
PFObject *object = [objects objectAtIndex:0];
[self setvalue:object];
[object saveEventually];
[object pinInBackgroundWithName:self.registerId];
}
else{
PFObject object = [PFObject objectWithClassName:@"register"];
[self setvalue:object];
[object saveEventually];
[object pinInBackgroundWithName:self.registerId];
}
}
];
}

-(void)setvalue:(PFObject *)object{
[object setObject:self.registerId forKey:@"register_id"];
[object setObject:[NSNumber numberWithFloat:self.amountIn] forKey:@"field1"];
[object setObject:[NSNumber numberWithFloat:self.amountOut] forKey:@"field2"];
[object setObject:[NSNumber numberWithInt:self.transactionType] forKey:@"trans_type"];
[object setObject:[NSNumber numberWithFloat:self.total] forKey:@"total"];
[object setObject:self.date forKey:@"date"];
[object setObject:self.username forKey:@"username"];
}

Hey @psiphone, this sounds about right.
A general recommendation - use smaller pins, since there is no limit on the total pin count.

We are also tracking overall LDS (local datastore) performance improvements in #32, and there is some information there around this.

Ohh, so if my rows in a table is 10k then will it increase time to pin an object?

[nlutsenko]

Yup. We have a somewhat linear dependency on number of objects in a pin, so yes - 10k objects will slow things down.

[Mohd-Aamir-M]

How much time it will take to pin an object if i have 10k rows in a customer table with 2 pointers and 5 string fields?

Hope this fixes in 1.9.0 else i will have to drop parse.
