Test seems flaky, will try rerunning again:

Checks are passing, the one failing is for parsing test results (saying the file is too large: https://github.com/apache/beam/pull/30772/checks?check_run_id=23251024301)

[github-actions]

Checks are failing. Will not request review until checks are succeeding. If you'd like to override that behavior, comment assign set of reviewers

[github-actions]

Assigning reviewers. If you would like to opt out of this review, comment assign to next reviewer:

R: @bvolpato for label java.

Available commands:

• stop reviewer notifications - opt out of the automated review tooling
• remind me after tests pass - tag the comment author after tests pass
• waiting on author - shift the attention set back to the author (any comment or push by the author will return the attention set to the reviewers)

The PR bot will only process comments in the main thread (not review comments).

instead of repeating these everywhere we create the builder how about creating a static create method that constructs the builder and adds defaults instead of calling the builder constructor directly. Could unify the other defaults as well.

pseudocode:
in AutoValue_WriteFiles.Builder

static Builder create() {
return new AutoValue_WriteFiles.Builder<UserT, DestinationT, OutputT>.Builder()
.setFileTriggeringByteCount(FILE_TRIGGERING_BYTE_COUNT) // 64MiB as of now
}

and make constructor private

I believe that you can override th builder constructor to set the defaults. That seems better in that it will have a single location instead of duplicated across different files.
