----------------------------------------------
Summary: Create HiveRelFactories
Key: HIVE-12542
URL: https://issues.apache.org/jira/browse/HIVE-12542
Project: Hive
Issue Type: Bug
Components: CBO
Affects Versions: 2.0.0
Reporter: Jesus Camacho Rodriguez
Assignee: Jesus Camacho Rodriguez
Calcite 1.5.0 introduced the use of RelFactories to create the operators. In
particular, RelFactories contains the factories for all the operators in the
system. Although we can still implement old rules by providing each individual
factory (the constructor is deprecated, but it won't be removed till Calcite
2.0.0 is out), new rules will only provide constructors based on RelFactories.
Thus, we propose to migrate immediately to the new interface.
