  • More testing (+ unit tests)
  • Query plan correctness issues
    • Datafusion plan typing issues
  • EXISTS clauses
  • IN clauses
  • ANY/ALL clauses
  • IsNull/IsNotNull
  • Correctness issue with COUNT(*) (requires adding left outer join to plan)
  • Support more pushdowns (e.g. limit, joins)
  • Optimizations from the paper are all missing (Out of scope?)
