--------------------------------
Summary: Move non-type specific column statistics to
ColumnStatistics object in ORC
Key: HIVE-5787
URL: https://issues.apache.org/jira/browse/HIVE-5787
Project: Hive
Issue Type: Improvement
Affects Versions: 0.13.0
Reporter: Prasanth J
Priority: Minor
Non-type statistics like min, max, numNulls etc. can be moved to
ColumnStatistics class. This avoids ugly checks like
{code} if (index instanceof IntegerColumnStatistics) {
return ((IntegerColumnStatistics) index).getMinimum();
} else if (index instanceof DoubleColumnStatistics) {
return ((DoubleColumnStatistics) index).getMinimum();
} else if (index instanceof StringColumnStatistics) {
return ((StringColumnStatistics) index).getMinimum();
{code}
