I suspect no, they probably care more about the iceberg parts than the DuckDB parts? but this is purely speculative.

i've also been spending a lot of time on pg_duckdb (and how to run it) as we prepare for launching 1.0 of that extension. Can't wait to share more

This practical example of how easy it is to bootstrap your observability is part of why I love working on DuckDB every day!

Another good strategy is partitioning your writes to object storage by date / time (i.e. by hour) so you can easily write naive queries for analysis and backfills, like `select * from 's3://my_bucket/year/month/day/hour/*.json'`
