如何遍历Avro文件中所有嵌套记录中的所有字段，并检查其类型中的某个属性？

import avro.schema
from avro.datafile import DataFileReader
from avro.io import DatumReader

schema = avro.schema.parse(open("your_schema.avsc", "rb").read())

reader = DataFileReader(open("your_data.avro", "rb"), DatumReader())

for record in reader:
    process_record(record)

def process_record(record):
    # 遍历记录中的字段
    for field in schema.fields:
        process_field(record, field)

def process_field(record, field):
    # 检查字段类型和属性
    if field.type == "record":
        # 如果字段是嵌套记录类型
        nested_record = record.get(field.name)
        if nested_record is not None:
            process_record(nested_record)
    elif field.type == "array":
        # 如果字段是数组类型
        array = record.get(field.name)
        if array is not None:
            for item in array:
                process_field(item, field.items)
    elif field.type == "map":
        # 如果字段是映射类型
        map = record.get(field.name)
        if map is not None:
            for key, value in map.items():
                process_field(value, field.values)
    else:
        # 其他类型的字段
        # 检查字段的某个属性
        if field.props.get("your_property") == "your_value":
            # 处理满足条件的字段
            process_field_value(record.get(field.name))

def process_field_value(value):
    # 处理字段的值
    pass
