Alternative to redis.keys(...)

Question

In the documentation, it strongly discourages the use of .keys() in a production environment. What would be an alternative to the following:

r = Redis()
keys = r.keys('RT*')
for key in keys:
    do_something()

Answer 1

SCAN is the recommended alternative for production usage.

redis-py includes a convenient SCAN iterator for that purpose, so what you can do is:

r = Redis()
for key in r.scan_iter(match='RT*'):
  print(key) # or do something
