Using Partial Property Update in Dash 2.9 for Handling Circular Callbacks

[wowwwn]

I’m really excited about the updates in Dash 2.9 and looking forward to applying them to my Dash app.

I have a question regarding the use of Partial Property Update in my callback. Does the Patch() function only work when there is a single callback output?

I’m dealing with Circular Callbacks to synchronize two components in my application. Any guidance on how to effectively utilize the Patch() function in this context would be greatly appreciated.

HI @wowwwn,

I’m not sure if I understand you correctly but take a look at the first example I shared here:

Sharing examples of partial update & allow_duplicate=True from Dash 2.9.2!

Hi all, recently I started playing around with partial updates and the allow_duplicate=True parameter. For my app the benefit of using the new features is huge. I thought I share two MRE do demonstrate the capabilities. change the trace color of selected traces, uses partial updates and duplicated outputs add annotations to a image displayed with px.imshow(), here you should take a look on the data size traveling from client to server depending on the button you click. First example, change…

I use Patch() and allow_duplicate=True
