Revert "[CALCITE-4817] Expand SubstitutionVisitor of Aggregate with max/min, which column is the group by list of target (xurenhe)" This reverts commit 74e97780add051cb71a122075e5bcbceb40e889c.
Apache Calcite is a dynamic data management framework.
It contains many of the pieces that comprise a typical database management system but omits the storage primitives. It provides an industry standard SQL parser and validator, a customisable optimizer with pluggable rules and cost functions, logical and physical algebraic operators, various transformation algorithms from SQL to algebra (and the opposite), and many adapters for executing SQL queries over Cassandra, Druid, Elasticsearch, MongoDB, Kafka, and others, with minimal configuration.
For more details, see the home page.
