> And also the ticket and "// TODO: BEAM-10396 use writeRows() when it's
available" appeared later than this functionality was added to
"JdbcIO.Write".

Note that this TODO has been moved around through a few refactors. It was
initially added last summer [1].
You're right that JdbcIO.Write's statement generation functionality was
added about a year before that [2]. It's possible that the author of [1]
didn't realize [2] was done. Or maybe there's some reason why it doesn't
work there?

+1 for Alexey's requests:
- Identify cases where statement generation in JdbcIO.Write is
insufficient, if they exist (e.g. can we just use it where that TODO is
[3]? If not what goes wrong?).
- Update documentation to avoid this confusion in the future.
