[CALCITE-4795] In class SqlBasicCall, make the "operands" field private (part 2) This commit is part 2 of 2, after release 1.28, and removes APIs marked 'deprecated to be removed before 1.29'. The 'operands' field is now an immutable list (that may contain null values). If a user calls setOperand, a new list is created. Therefore operands do not need to be cloned when the call is cloned. The 'expanded' field has been removed, because it is typically false. There is a sub-class where isExpanded() returns true.
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.
