FATE数据接入指南

1. upload

fate提供upload组件供用户上传数据至fate所支持的存储系统内(默认eggroll)

用法如下:

# cli
python fate_flow_client.py -f upload -c $config_path

# fate client
flow data upload -c $config_path

• eggroll

      python fate_flow_client.py -f upload -c examples/upload/upload_to_eggroll.json 

      flow data upload -c examples/upload/upload_to_eggroll.json 

• mysql

      python fate_flow_client.py -f upload -c examples/upload/upload_to_mysql.json 

      flow data upload -c examples/upload/upload_to_mysql.json 

• hdfs

      python fate_flow_client.py -f upload -c examples/upload/upload_to_hdfs.json 

      flow data upload -c examples/upload/upload_to_hdfs.json 

2. table bind

若用户的数据已经存在fate所支持的存储系统内,可通过table bind将真实存储路径映射到fate存储表

用法如下:

# cli
python fate_flow_client.py -f table_bind -c $config_path

# fate client
flow table bind -c $config_path

• mysql

      python fate_flow_client.py -f table_bind -c examples/table_bind/bind_mysql_table.json 

      flow table bind -c examples/table_bind/bind_mysql_table.json 

• hdfs

      python fate_flow_client.py -f table_bind -c examples/table_bind/bind_hdfs_table.json 

      flow table bind examples/table_bind/bind_hdfs_table.json
