   Confirmed with https://github.com/apache/polaris/pull/1092 and cranking up 
to concurrency of 100 that I get 99 failures and 1 success:
   
       $ ./gradlew :polaris-benchmarks:gatlingRun
       Configuration on demand is an incubating feature.

   Whereas if (1) *or* (2) aren't fixed, it shows reliable corruption in the 
backend with duplicates.
   
   If (1) and (2) are fixed but not (3), then the database remains correct with 
1 unique table, but there will be erroneous `200` return codes. The `200` 
responses do return the "correct" metadata JSON (the really committed one, not 
new attempts to commit), but they should be 409s nonetheless.
