Share a dict with multiple Python scripts

Question

I\'d like a unique dict (key/value) database to be accessible from multiple Python scripts running at the same time.

If script1.py updates

Answer 1

I would use a pub/sub websocket-framework, like Autobahn/Python, with one script as a "server" and it handles all the file communication but it depends on scale maybe this could be Overkill.

Answer 2

I'd consider 2 options, both are embedded databases

SQlite

As answered here and here it should be fine

BerkeleyDB

link

Berkeley DB (BDB) is a software library intended to provide a high-performance embedded database for key/value data

It has been designed exactly for your purpose

BDB can support thousands of simultaneous threads of control or concurrent processes manipulating databases as large as 256 terabytes,3 on a wide variety of operating systems including most Unix-like and Windows systems, and real-time operating systems.

It is robust and has been around for years if not decades

Bringing up redis/memcached/ whatever else full-fledged socket-based server that requires sysops involvement IMO is an overhead for the task to exchange data between 2 scripts located on the same box
