将多个json文件追加到一起，并使用Python输出1个Avro文件

import json
import avro.schema
from avro.datafile import DataFileWriter
from avro.io import DatumWriter

schema = avro.schema.Parse('''
    {
        "type": "record",
        "name": "JsonData",
        "fields": [
            {"name": "data", "type": {"type": "map", "values": "string"}}
        ]
    }
''')

writer = DataFileWriter(open('output.avro', 'wb'), DatumWriter(), schema)

json_files = ['file1.json', 'file2.json', 'file3.json']

for file in json_files:
    with open(file, 'r') as f:
        json_data = json.load(f)
        writer.append({"data": json_data})

writer.close()
