Another way to go about it could be:

1. get a set of all the application ids from the subscriptions that you found
2. search applications to recuperate all the applications with those ids
3. create a HashMap in your class with the key as the application Id and the value as the application name or application
4. for each subscription in your list, create an update model with the subscription id + application name, found via the HashMap with the subscription's application id

I'm not sure if this would be more "efficient", but it would be less network calls instead of calling the DB for every subscription that you find. WDYT?

Being inspired by your suggestion, I decided to execute 1 bulkAction per 1 application, so that we have flat number of updates. What do you think now?

@jhaeyaert can you think about any further optimization/is this approach good enough for prod?

I think the way it is done is ok. I would add a split into bulks of, let's say 1000, instead of having 1 single bulk to avoid loading all in memory. We already saw > 90k applications in some hard cases.
