Update many (different) docs using BulkWrite?

Is it possible to update different documents, provided as a Slice in one bulk-operation?

From what I read, we have to set the filter on the opdateOneModel., so isn’t this a single operation?

I mean, creatng a WriteModel for earch document in the slice (“batch”) I want to process, doesn’t feel right. Am I on the right path here?

In other words: What’s the best way to perform updates with different values to different documents (but always the same field of these documents)

well, I did it that way and it works quite fast
(only using tiny data on my dev VM)
