slowness with KCSQuery()
Rami,
- Can you log the timings in the comments.OnPreFetch() hook as well as the comments.OnPostFetch() hook ? That way we will know how much time is actually spent in fetching the entities and the remaining time would be due to the network.
- Also once you do the above analysis, can you also try using the KCSCachePolicy.NetworkFirst.rawValue?
Let me know the results for the above 2 points.
Thanks,
Pranav

Pranav,
thanks for your reply .
first i don't know how to make the log time in the hook if possible please give me the correct way to do it .
second i have try the "KCSCachePolicy.NetworkFirst.rawValue?" and it seems its a slower then the "KCSCachePolicy.LocalFirst.rawValue"
Thanks,

Rami,
Please take a look at the Business Logic reference, the logger and moment modules:
http://devcenter.kinvey.com/html5/reference/business-logic/reference.html
http://devcenter.kinvey.com/html5/reference/business-logic/reference.html#logger-module
http://devcenter.kinvey.com/html5/reference/business-logic/reference.html#moment-module
Here's a small snippet to get you started:
var logger = modules.logger;
var theMoment = modules.moment();
logger.info("Start Time" +theMoment );
Thanks,

Rami,
I have few questions for you:
- How many records are present in that collection? How many columns are present?
- Are you using any hooks for that collection?
- What is Kid and name of your app? Also what SDK version you are using?
- Do you consistently see the same timing for it or was it better earlier and then deteriorated?
- If you change the caching policy does it make any difference?
Thanks,
Pranav

Pranav,
thanks for your reply .
1 - kindly check the attached Screenshot
2 - no i am not using any hooks
3 - i did not understand ? the SDK V = KinveyKit-1.40.8
4 - i am using the query in other page of the App but without the "withExactMatchForValue: DV.NameOfRest)" and working fine and fast and its calling more then 80 record with image .
5 - i have change it many time but its no deferents , and please which one of "caching policy" is better ?
Thanks ,

i am using KCSQuery to download comments and usernames from the collection from the backend as below code the issue that is that when i use
let query = KCSQuery(onField: "Rest_Name", withExactMatchForValue: "Name")
its toke long time to download more then 10 sec
func NumberOfCells() {
let collection = KCSCollection(fromString: "Comments", ofClass: NSMutableDictionary.self)
DownCells.storeComments = KCSCachedStore(collection: collection , options: [ KCSStoreKeyCachePolicy : KCSCachePolicy.LocalOnly.rawValue ])
let query = KCSQuery(onField: "Rest_Name" , withExactMatchForValue: DV.NameOfRest)
DownCells.storeComments.queryWithQuery(query,withCompletionBlock: { (objectsOrNil: [AnyObject]!, errorOrNil: NSError!) -> Void in
if errorOrNil == nil {
//extract just the Value field from the entities
for d in objectsOrNil as! [NSMutableDictionary] {
self.userName_.append((d.valueForKey("User_Name") as? String)!) // fill the array of Users Name
self.CommentsValue_.append((d.valueForKey("Comments") as? String!)!) // fill the array of Comments
self.tableView.reloadData()
// insert the names of the user comments to doownload ther images
// download the image for the user
self.DownloadImages((d.valueForKey("User_Name") as? String)! + ".jpg") // fill the array of Images Name
self.Loading.stopAnimating()
self.Loading.hidesWhenStopped = true
}
}
self.tableView.reloadData()
},withProgressBlock: nil )
}
its working fine and download all what i need but toke long time and this will effect the app , is there any way to support me to make it faster or any deferent way to download if my way is wrong
