-----------------------------------------
Summary: Prevent optimization of non-deterministic functions
Key: CALCITE-2823
URL: https://issues.apache.org/jira/browse/CALCITE-2823
Project: Calcite
Issue Type: Bug
Components: core
Reporter: Siddharth Teotia
Assignee: Julian Hyde
RexSimplify and RexProgram optimize expressions like A() = A() to true, but if
A() is a non-deterministic expression, this optimization is invalid. Change
RexSimplify and RexProgram to check if expression is deterministic or not, in
order to decide about the optimization.
