shared-memory-dict 0.2.0

A very simple shared memory dict implementation

Shared Memory Dict

A very simple shared memory dict implementation.

Requires: Python >= 3.8

>> from shared_memory_dict import SharedMemoryDict
>> smd = SharedMemoryDict(name='tokens', size=1024)
>> smd['some-key'] = 'some-value-with-any-type'
>> smd['some-key']
'some-value-with-any-type'

The arg name defines the location of the memory block, so if you want to share the memory between process use the same name

Installation

Using pip:

pip install shared-memory-dict

Locks

To use uwsgidecorators.lock on write operations of shared memory dict set environment variable SHARED_MEMORY_USE_UWSGI_LOCK.

Django Cache Implementation

There's a Django Cache Implementation with Shared Memory Dict:

# settings/base.py
CACHES = {
    'default': {
        'BACKEND': 'shared_memory_dict.caches.django.SharedMemoryCache',
        'LOCATION': 'memory',
        'OPTIONS': {'MEMORY_BLOCK_SIZE': 1024}
    }
}

This implementation is very based on django LocMemCache

Install with: pip install "shared-memory-dict[django]"

AioCache Backend

There's also a AioCache Backend Implementation with Shared Memory Dict:

From aiocache import caches

caches.set_config({
    'default': {
        'cache': 'shared_memory_dict.caches.aiocache.SharedMemoryCache',
        'size': 1024,
    },
})

This implementation is very based on aiocache SimpleMemoryCache

Install with: pip install "shared-memory-dict[aiocache]"
