persistentdict

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
