I am thinking when will be the case/need for that. Do you have some situations in mind ?

Crash reporting - we need write it as log or RUM event in a blocking manner.

are we creating a writer every time we are writing something ?

yes, every time we request write context (which should be short-living), because writer is associated with a particular batch file

Damn...I am thinking that for SR I will have to write tons of events....meaning that we will be creating those writers all the time. Aren't we afraid of too many objects there ? I mean I know they are not so heavy but was thinking that maybe if we could do it differently 🤔

We can profile it. Anyway, the number of these objects will be much less that number of snapshot/wireframes objects to write :)

What does this PR do?
This PR may look big, but essentially it does the following:
Storage#writeCurrentBatchimplementation is now async (ConsentAwareStoragetakes an executor), meaning I/O access inside this method is happening on the worker thread and callback is invoked on the worker thread as well.EventBatchWriterinto a dedicated class (and moved tests as well), becauseConsentAwareStorageand its tests were too big already. Introduced also a no-op implementation of writer if there is no batch file or consent is not granted - this is where the most of the diff comes from.This change is needed to make
FeatureScope#withWriteContexttruly async to be able to implement event write context further.Review checklist (to be filled by reviewers)
