Yet another [1] dictionary backed by Redis DB.
We use Redis` 'hash' type [2] and store whole dictionary in one hash.
Usage:
from persistentdict.dict_in_redis import PersistentDict
db = PersistentDict(hash_name="my-persistent-dict")
# add key to the db with a value
db['key'] = value
# show whole dictionary
print(db)
# iterate over keys & values in db
for key, value in db.items():
do_something(key)
# do sth with key if it is in db
if key in db:
do_something(key)
# delete key from db
del db['key']Installation:
pip3 install persistentdict[1] Alternatives: persistent-dict, durabledict
[2] https://redis.io/topics/data-types-intro#hashes is basically Python's dict, but values can be strings only, so we use json serialization
