Hi all,
I have a data record with this values:
- public key
- car_name
- description
- current_speed
The issue is that when I want to retrieve the data to be displayed in a grid I'm interested in retrieving the whole set. However when I want to update an image displaying the speed I only want to retrieve the speed and pk. And if it is possible update the cell in the grid with the current speed.
Let's say that once retrieved the name and description, it is static for the whole life of the application, while the speed isn't.
How is it possible to achieve this? The idea is to reduce the amount of data sent through the network.
Thanks
