Streaming Tunnel是MaxCompute的流式数据通道,您可以通过Streaming Tunnel向MaxCompute中上传数据,本文为您介绍使用Python版Streaming Tunnel SDK上传数据的简单示例。
注意事项
Streaming Tunnel仅支持上传数据,下文为您介绍一个简单的数据上传的Python SDK示例。
上传示例
import os
from odps import ODPS
from odps.tunnel import TableTunnel
# 确保 ALIBABA_CLOUD_ACCESS_KEY_ID 环境变量设置为用户 Access Key ID,
# ALIBABA_CLOUD_ACCESS_KEY_SECRET 环境变量设置为用户 Access Key Secret,
# 不建议直接使用 Access Key ID / Access Key Secret 字符串
odps = ODPS(
os.getenv('ALIBABA_CLOUD_ACCESS_KEY_ID'),
os.getenv('ALIBABA_CLOUD_ACCESS_KEY_SECRET'),
project='<your-default-project>',
endpoint='<your-end-point>',
)
tunnel = TableTunnel(odps)
table = odps.get_table('<table_name>')
upload_session = tunnel.create_stream_upload_session(table.name, partition_spec='pt=test')
with upload_session.open_record_writer() as writer:
record = table.new_record()
record[0] = 'test1'
record[1] = 'id1'
writer.write(record)
record = table.new_record(['test2', 'id2'])
writer.write(record)
