Hi all, Calcite-1058 made RelBuilder.filter(false) and RelBuilder.limit(0, 0) simplify to empty(), i.e., empty logical values. However, Hive ASTConverter is not able to deal with empty logical values. I saw it was resolved in Calcite 1.6 but it was not included in the 1.6 snapshot when we tested against Hive. I would assume that replacing RelBuilder class with a newly created HiveRelBuilder would be expensive. Could you please let me know if you have any better ideas? Thanks!
