[轉載]Python在redis中存取DataFrame數據

轉載自：Python在redis中存取DataFrame數據

1、通過pickle序列化的方式

import pandas as pd
import pickle
import redis
rs = redis.StrictRedis(host='127.0.0.1')

df=pd.DataFrame([range(5)]*5,index=list('HELLO'),columns=list('HELLO'))

df_bytes = pickle.dumps(df)
rs.set('test_df', df_bytes)

df_bytes_from_redis = rs.get('test_df')
df_from_redis = pickle.loads(df_bytes_from_redis)
print(df_from_redis)

2、通過df.to_msgpack的方式

import pandas as pd
import pickle
import redis
rs = redis.StrictRedis(host='127.0.0.1')

df=pd.DataFrame([range(5)]*5,index=list('HELLO'),columns=list('HELLO'))

df_bytes = df.to_msgpack()
rs.set('test_df', df_bytes)

df_bytes_from_redis = rs.get('test_df')
df_from_redis = pd.read_msgpack(df_bytes_from_redis)
print(df_from_redis)
