Did not feel like a 20 min video. Great explanation . Rightly explained and stated all key points . Thank you

The 5 sec wait, is the wait time for a single child thread ? or the max time for all the child threads to finish ?

Thank u Victor for the awesome explaination.
Just wanted to add one thing.

We can use Aggregate Source option in Datapage when subsequent API calls are dependent on each other

[vivekkale]

what if one the 3 api calls fails and does not load data, how do we handle such scenario,

[MrPraveensiva]

We can execute the same with the run in parallel option on the connect rules with the connect wait option, but I prefer the data page asynchronous option. We can also do the same by executing the activities asynchronously with the async activity method and with the connect wait option. But to do this the activity should be of type aync.
