java - How to do a bulk update in Firestore

Question

I'm using Cloud Firestore and have a collection of documents. For each document in the collection I would like to update one of the fields.

Using a transaction to perform the update would be inefficient because I do not need to read any of the data while updating it.

Batch updates seem like the right direction, however the docs do not include examples of updating multiple docs at once. See here: Batched Writes
