Writing Column Statistics

[jigleski]

"DataColumn.Statistics" is only populated when reading from what I have tested. I'm working on a project to write parquet files, but once I have created a new instance of a DataColumn such as with the code snippet below the statistics are not populated nor do I see a way to set them myself since I can only get the value for the Statistics fields.
else if (sig.type == typeof(long))
{
long[] col = new long[cnt];
for (int i = 0; i < cnt; i++)
col[i] = sig.ExtractBitValue_long(msgArray[i].Data);
columns[s] = new DataColumn(schema.DataFields[s], col);
}

Seems a bit vague. How are you checking statistics are not populated?
