Time-consuming mapping of Flux and Mono into DTO
I've got 2 end-points returning the same data in two different JSON-formats.
The first end-point returns a JSON-array, and starts the response right away.
@Format("yyyy-MM-dd") cutoffDate: LocalDate
): Flux = snapshotDao.getAllSnapshots(cutoffDate)
The next end-point that returns a paged result, is more sluggish. It starts the response when both streams are completed.
