Best way to Patch and Display results

Hello all, I have a question that I've toyed around with in my mind and was trying to figure out if its the right way to do things or not.


So I'll attach a screenshot, sadly, a lot is redacted so I don't share anything sensitive, but I think it'll get my point across anyways.


 This is a small part of my app I've been making and updating for over a year now. For the most part it does everything that I want it to do, its just very very slow. My backend is a SQL server View. When there are only a few lines, it runs decent enough, but if I have a lot of lines, like over 20ish, it tends to be a bit sluggish. 

Currently, today, this gallery that has all the lines is loading directly from the SQL View. When I use the green check or red x to approve or reject that line, it preforms a patch on the table that holds the data and then refreshes the view so that this gallery will reflect the changes. But that is where it is so slow. I've heard about using collections but never been brave enough to put in the effort to try it. But basically, I wanted to describe the change I'm wanting to make and get feedback if that is how I should be doing it, or if I should stick with what I have now.

So what I'm wondering is if I should be loading that entire view into a collection, and then have the gallery load from the collection. And when I need to do a patch, I would still patch the table, but I would also patch the collection so it reflects the change. I'm thinking that patch on the collection triggers the refresh of the gallery, and then I don't have the app waiting for the view to refresh meaning it would be faster. At least that is my theory. Am I on the right path, or should I be going a completely different direction?

Hi @Jsunnb ,


Using collection is considerably faster compared to one-by-one approach.

The only thing is I have seen, bulk update works very fast on SharePoint records. I have personally used Dataverse and collection. Although there's delay compared to SP since it sends request 1 by 1 to Patch to the server whereas for SP it goes parallelly. (This is explained in 1 of Shane Young's YT video).


[Personally, I have been using collection for bulk updates for a long time. There's another method by passing JSON object to Power Automate and let Flow update records in SQL. This too will take moderate time as it should, but your App can be less loaded on performance and be lightweight.]


Now coming to SQL, I haven't tried it. With respect to your use-case. I'd say you should go with collections and try the performance side-by-side.

Create a new screen and drop the gallery and insert the changes.

For your Tick or Cross, save the data into a collection with the response for each record.


Note: Collection always need to have primary ID/key/GUID to update existing record. So, make sure you have it in collection.


Then try Patching the collection to your Table. If SQL supports then entire collection will be updated at once.

If not, then you can loop and patch request one-after the other.


Hope this helps

Thank you for the input, I'll look at how I can use a collection to patch a table and then do a test. It sounds like there might be some savings there and would be worth the effort of making the change.

So I did a quick test and had it create a collection and do the gallery off the collection. It still takes the same time to populate the gallery since it still has to load the collection from the view. But once I have it, all the patching happens very fast since you see it instantly almost for the collection which is what I do first. And then the patch to the table just happens in the background and takes it's time.


Question though, this will mean people will be able to click multiple lines and initiate the patching potentially before the last one finished. How does that work, first in first out? Will the table patching not being done slow down the next collection patch?

It'll be a pretty extensive update to see it working in runtime so I thought I'd see what everyone already knew

Hi @Jsunnb ,


So, what you can do to make it more faster and efficient.

1. You can create records in collection for what you make updates to your gallery records. If you tick/cross 5 records then you add only 5 records into your collection.

2. Keep a single button on top, say "Save Updates" and then apply formula to Patch all records to the system. Once successful, clear the collection for next updates. Refresh the Datasource to see updates made to your list.


Let me know, which method you are choosing since the answer for your question will depend on it.


Hope this helps
