读取avro文件的schema

首先安装包

pip install avro-python3

然后在py文件倒入包

from avro.datafile import DataFileReader, DataFileWriter
import avro.io
reader = avro.datafile.DataFileReader(open('./account_id_schema_new.avro',"rb"),avro.io.DatumReader())
schema = reader.meta
print(schema)

显示的效果如下:

{'avro.schema': b'{"fields": [{"type": ["null", "string"], "name": "ACNO"}, {"type": ["null", "double"], "name": "FIELD_1"}, {"type": ["null", "double"], "name": "FIELD_2"}, {"type": ["null", "double"], "name": "FIELD_3"}], "type": "record", "name": "Root"}',
 'avro.codec': b'null'}
