[ADR] Against the use of Lightweight Transaction in Cassandra code base

Rely on event sourcing to maintain a projection of ACLs that do not rely on LWT or SERIAL consistency level.

LWT are required for eventSourcing. As event sourcing usage is limited to low-usage use cases, the performance
degradations are not an issue.

I'm probably missing your point, but for me these 2 sentences seems completely contradictory.

I think I got it reading your code. You assume that with event sourcing you use LWT only for writes and that you have a projection for reads.
This explanation is missing.
And then you are missing an explanation of why you cannot do that directly for every usage of LWT.
(note that I have nothing against event sourcing, and I think it's very valuable in particular for things like ACL, but your explanation is incomplete for me)

I noticed clearly that related works requires more discussions and mentionned alternative ways to potentially generate monotic integers.
