C:\Python27/Scripts\levitas-memstorage-service.py -s my_site.settings -l C:\levitasmemstorage.log -v install
C:\Python27/Scripts\levitas-memstorage-service.py start

Example

Create a settings.py module:

memstorage_address = ("127.0.0.1", 54678)
memstorage_authkey = "my_secret_key"
memstorage_objects = {"my_dict": dict}

Start the memstorage server:

levitas-memstoraged -s settings -v foreground

Now you can access the memstorage

from levitas_memstorage import memstorage

# Get a proxy object of my_dict
my_dict = memstorage().my_dict()

# Write something into the dict
my_dict["some_key"] = "some_value"
