Storing data in memcache

The memcache is an in-memory, key-value database store, just like Redis. After you install and run the memcached server, install the memcache Python client using the following command:

$ pip3 install python3-memcache

The code in the ch-08.ipynb file creates a memcache client and then stores the DataFrame to memcache with an auto-expire value of 600 seconds. The code is similar to the code for Redis:

import memcache 
import statsmodels.api as sm 
import pandas as pd 
 
client = memcache.Client([('127.0.0.1', 11211)]) 
data_loader = sm.datasets.sunspots.load_pandas() 
df = data_loader.data 
data = df.T.to_json() 
client.set('sunspots', data, time=600) 
print("Stored data to memcached, auto-expire after 600 seconds") 
blob = client.get('sunspots') 
print(pd.read_json(blob))
