------------------------------------------------
Summary: Extend simplification of expressions with CEIL function
over date types
Key: CALCITE-2334
URL: https://issues.apache.org/jira/browse/CALCITE-2334
Project: Calcite
Issue Type: Improvement
Components: core
Affects Versions: 1.17.0
Reporter: Jesus Camacho Rodriguez
Assignee: Julian Hyde
CALCITE-2332 disables simplification of CEIL function due to correctness issues.
{{FLOOR}} and {{CEIL}} cannot be handled with the same logic. For instance,
{{CEIL(CEIL(x TO HOUR) TO YEAR)}} cannot be simplified, e.g., '2011-12-31
23:59:59', while {{FLOOR(FLOOR(x TO HOUR) TO YEAR)}} can be simplified. Hence,
we need new logic to enable simplification of CEIL function on date types.
