Deserialize list of structs

[fodor-lori]

I have some Parquet files with the following schema (as displayed in Apache Parquet Viewer):

...
field (String)
rows (List)
  array_element (Struct)
    field_1 (String)
    field_2 (Int64)
    ...

However, the schema I get in ParquetReader.Schema for the previous example looks like this:

dataFields[0] = "field";
dataFields[1] = "rows/bag/array_element/field_1";
dataFields[2] = "rows/bag/array_element/field_2";

At the end of the day, all of this should deserialize into the format below (or something like this, even with intermediate models if necessary).

class ParquetData {
  public string field { get; set; }
  public List<RowData> rows { get; set; }
}

class RowData {
  public string field_1 { get; set; }
  public int field_2 { get; set; }
}

I tried to create intermediate models, such as bag (what is bag even?) and array_element, tried to specify JsonPropertyName("..."), but none of this helped deserializing this list of structs in the Parquet files.

Are relatively complex use cases like this even supported? If so, do you have some ideas of how to make the deserialization work?

This lib supports all the complex data types, should be no problem. Can you drop an example of the file you are trying to read? Also have you tried to open it with https://aloneguid.github.io/parquet-online/?
