--------------------------------------
Summary: Method RelMdUtil$numDistinctVals() wrongly return zero if
the method input domainSize is a very large value
Key: CALCITE-5431
URL: https://issues.apache.org/jira/browse/CALCITE-5431
Project: Calcite
Issue Type: Bug
Components: core
Affects Versions: 1.33.0
Reporter: Yunhong Zheng
Fix For: 1.33.0
Method {{RelMdUtil$numDistinctVals()}} wrongly return zero if the method input
{{domainSize}} is a very large value. If {{domainSize}} is a very large value
(like 2 x 10^16), Math.log(1.0 - 1.0 / dSize) will return 0, and {{domainSize}}
will be set to 0, which is unreasonable in this scenario.
