Harshvardhan Gupta commented on DERBY-6942:
-------------------------------------------
Yes, the cardinality and cost estimates are both going to be more accurate,
typically in case of loop joins cost is estimated as (number of rows in outer
tables * cost for single row match in inner table).
> Utilise additional statistics for selectivity estimates.
