Help wanted : statistics on a column

[thomasroshin]

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,
