--------------------------------
Assignee: Prasanth J
> 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
> Assignee: Prasanth J
> Priority: Minor
> Labels: orcfile
>
> 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}
