Ashutosh Chauhan commented on HIVE-10226:
-----------------------------------------
Using long column in metastore table to store max and min date is fine, but
reusing {{LongColumnStatsData}} in thrift interface to return result not so
much. I think we should add new thrift structure {DateColumnStatsData}}
something like :
{code}
struct DateColumnStatsData {
1: optional Date minDate,
2: optional Date maxDate,
3: required i64 numNulls,
4: required i64 numDVs
}
{code}
and than metastore after retrieving # of days from backend, should compute
Date, populate this struct and return results back to client.
> Column stats for Date columns not supported
