AvroHelper.Generators 1.0.0

AvroHelper

Source generator to make implementing ISpecificRecord less of a pain.

Usage

Install NuGet package

dotnet add package AvroHelper.Generators

Apply attribute to your partial class

Any property with an AvroColumnAttribute will be included in mapping.

using AvroHelper

[GeneratedAvroRecord]
public partial class MyRowDto
{
  public string SomeId { get; set; }
  
  [AvroColumn(0, ColumnName = "some_RiDiCuLoUs_name")]
  public string SensibleName { get; set; }

  [AvroColumn(0, ColumnName = "DATE_COLUMN", UnderlyingType = "int", LogicalType = "date")]
  public DateTime? DateColumn { get; set; }
}

The souce generator will implement ISpecificRecord with implementations of the Schema, Get, and Put. It will only add the Schema if your class does not already have a Schema Get method, so if you don't want to use the generator's schema, just implement that yourself.

var datumReader = new SpecificDatumReader<MyRowDto>(schema, schema);
using var stream = avroRows.SerializedBinaryRows.Memory.AsStream();
var decoder = new BinaryDecoder(stream);

while (stream.Position < stream.Length)
{
    var @record = datumReader.Read(null!, decoder);
    yield return @record;
}
