我现在想给redis添加数据。
我的目的是分割数据,并将其一点一点地插入redis。
在redis中插入pandas.dataframe之后,我想添加数据
我们现在已经在redis中插入了dataframe,但是我们不知道如何保存和添加现有的数据。
例如:

log_df_v1 ## DataFrame_v1
session_id                               connect_date     location categories join    page_out

第一步。Dataframe到redis set

r = redis.StrictRedis(host="localhost", port=6379, db=0)
log_dic = log_df_v1.to_dict()

log_set = json.dumps(log_dic,ensure_ascii = False).encode('utf-8')
r.set('log_t1',log_set)

是的
第二步。从redis获取数据,使之成为dataframe

log_get = r.get('log_t1').decode('utf-8')
log_dic = dict(json.loads(log_get))
data_log = pd.DataFrame(log_dic)
data_log
session_id                               connect_date     location categories join    page_out

第三步(问题)。我想向redis添加Dataframe(logdfv2)。但是,我需要保留现有的Dataframe(logdfv1)

log_df_v2 ## DataFrame_v2
session_id                              connect_date        location    categories  join    page_out

 20002    ea348aa8-aa52-4ee2-84da-f000020c1ecf    2019-12-29 16:03:15 경상북도    1   0   0

我想要的结果是:

log_get = r.get('log_t1').decode('utf-8')
log_dic = dict(json.loads(log_get))
data_log = pd.DataFrame(log_dic)
data_log
session_id                               connect_date     location categories join    page_out

如何将logdfv1和logdfv2插入redis?
我只想在redis上保存数据。
请帮帮我。。。
