I would like to express complex merge into logic in iceberg tables
Describe the solution you'd like
have all the powers of Apache spark merge into ( WHEN MATCHED , WHEN NOT MATCHED BY SOURCE/BY TARGET ... )
Describe alternatives you've considered
2 operations ( delete then insert ) but without "lock" a concurrent query can occur between the 2 operations
