Memory exhaustion error when updating a large number of entities

Is this a duplicate of 🐛 Use QueueWorker to avoid timeouts when updating large number of references Needs work ?
Could you please join forces to fix the issues and provide a well tested MR against 2.x-dev?

Thanks :)

I would say this is a duplicate of 🐛 Use Batch API to avoid timeouts when updating large number of references Needs work since both use batch api as a solution. Marking this one as duplicate since the other one has more recent activity, code is very similar.
