We have those pointless documents used by architects at my place of work, most of them have something on the lines of,
Micro services, Kafka, Kubernetes, because what if we have a billion users compared to the current 4k users.
GraphDB, what if SQL would not be enough
ElasticSearch, what if we have to do full text search along with stats.
But most of these documents are just short for any of these, "I want to try this new architecture/technology because it's fun, my colleague at a FAANG uses it, I've read the BOOK, and it looks good on my CV".
When they jump to design the next Big project, we have to deal with their decision, having twice as many services than our team, having to keep all the above mentioned DBs and technologies in sync which is of course a simpler problem than making those "big architecture decisions".
Sorry for the rant :(
