Answer 1

hscan seems much quicker than scan, better use hscan, only if you are sure about the key, if you need to search all keys then use scan

for name in r.hscan_iter('live_AP_460000','name'):
   print(name) #for a single child key

for hash in r.hscan_iter('live_AP_460000'):
   print(hash) #for all child keys

hscan is quicker than scan, only if you are searching for a correct key, else to fetch all keys with some similar pattern, go for scan. For reference. How to search a key pattern in redis hash?

Try the SCAN command like this :

r = Redis(....) #redis url
for user in r.scan_iter(match='userinfo_*'):
  print(user)
