1 month ago right now, execution of nodes happens in sequence.
example: in reactflow, need to find a way to run two nodes using the previous node has finished generation of output.
here is some guidance on custom nodes in reactflow:
I have worked on this type of issue in one of my project, where earlier all nodes are running sequentially, I wanted to make them run in parallel, So basically I wrote an algorithm ( just a dfs 😂 ) , in this algo what I did was, first i created one map which indicates which node is connected to which node, then I created a list in which all sequences (all paths ) from source to desination are mentioned ( I did this using Graph concept , first created an adjacency list and used dfs to map all the paths), for example [ { 0->1->2->4}, {0->1->3->4}] , here 2 and 3 are conneceted with 1 , here my source is 0 and destination is 4.
After getting the list [ { 0->1->2->4}, {0->1->3->4}], I used promise.all to execute both the path in parallel, it made my program very fast and reduced the time of execution from 17 seconds to 4 seconds
fyi :- . 4 seconds seems slow but it takes this much time because it is calling a lot of functions in the backend( quite complex project 😉).
