----------------------------------
Summary: Filter estimate should always be non-negative
Key: SPARK-36079
URL: https://issues.apache.org/jira/browse/SPARK-36079
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 3.2.0
Reporter: Karen Feng
It's possible for a column's statistics to have a higher `nullCount` than the
table's `rowCount`. In this case, the filter estimates come back outside of the
reasonable range (between 0 and 1).
