collecting Monos on each subscribe() from db operation

Question

I want to do db update to every record. I am using Mono for every record update, this work fine with .block() but giving unpredicatable result when using .subscribe(). Since .block() is not right approach for large number of records, I thought to combine all mono db calls and return a combined result as success for failure but since .subscribe() returns Disposabe object - I am not able to collect all Monos in List or not able to use Mono.zip() or any other way of collecting monos

for(Record record : records){
List<Mono<Void>> monos = dataStore
     .set(key, value) //this is for db insert that returns Mono<Void> for every record
     .subscribe() // error as return type is not Mono<Void>
}

Mono.zip(monos) 
     .subscribe() //error as return type is not Mono<Void>```
