Help wanted : statistics on a column #53

Open thomasroshin opened 4 years ago

thomasroshin commented 4 years ago

I am reading a parquet file and would like to get the statistics on the filelds (min/max) . Is it possible? Currently the statistics on a field is coming "undefined" :

MarginRate: { name: 'MarginRate', primitiveType: 'INT64', originalType: undefined, path: [ 'MarginRate' ], repetitionType: 'REQUIRED', encoding: 'PLAIN', statistics: undefined, compression: 'UNCOMPRESSED', typeLength: undefined, rLevelMax: 0, dLevelMax: 0 }

Thank you for your time.

regards,
