I can get one Key/Value from Redis with Python in this way:
import redis
r = redis.StrictRedis(host='localhost', port=6379, db=0)
data = r.get('12345')
How to get values from e.g. 2 keys at the same time (with one call)?
I tried with: data = r.get('12345', '54321') but that does not work..
Also how to get all values based on partial key?
e.g. data = r.get('123*')
You can use the method mget to get the values of several keys in one call (returned in the same order as the keys):
data = r.mget(['123', '456'])
To search for keys following a specific pattern, use the scan method:
cursor, keys = r.scan(match='123*')
data = r.mget(keys)
(Documentation: https://redis-py.readthedocs.io/en/stable/#)
data = r.get('123*')
r.scan(match='123*') to get a list of keys that match the given pattern, and then use mget afterwards.
keys(pattern='123*') instead of scan, because to fetch all marching keys you should use scan's cursor argument and iterate till the end.As @atn says: (and if using django)
from django_redis import get_redis_connection
r = get_redis_connection()
data = r.keys('123*')
works now.
with Django, you can directly do this that works for redis and other cache backends :
cache_results = cache.get_many(
(
cache_key_1,
cache_key_2,
)
)
cache_result_1 = cache_results.get(cache_key_1)
cache_result_2 = cache_results.get(cache_key_2)
