Hello, I am just starting to explore Calcite, especially related to its application to Hive. As I understand it, Calcite takes as input the following:
1. An SQL operator tree 2. A set of rules (pattern based) that define alterations to the three 3. A cost model for basic operations. Given these, calcite explores the space of all possible alterations (based on the rules) and returns the one with least cost. Is there an interface for Calcite to return multiple Operator trees, say for example, all trees with cost below a threshold ? If yes, pointers to it would be great. Thanks Raajay
