You'll see a performance benefit way before 100k rows depending on the size of each row, especially with sorting. It might save you guys a ton of CPU hosting wise, depending on how this all works, to track slow queries and auto add indexes. Way worth the write overhead in most cases.
It’s likely that most of their customers would only have a few hundred or thousand rows where indexing may not actually matter after all. Otherwise I’m sure they would’ve prioritized it.
