Experimental one-cell STM for FaaS

Project description

FaaS-based STM

This is a small library that attempts to do STM to update stored state in an object-storage system.

It also interacts with the Slack API.

The whole thing works by saving external effects until the STM commit passes; at that point, the external effects are committed also.


This can be installed in a Fn-style serverless function like this:

import logging

from slacker import Text, BaseDispatch, handle, debounce

LOG = logging.getLogger(__name__)

def handler(ctx, data=None):
    LOG.debug("got request: %s", data)
        response = handle(ctx, data, bot_class=MyBot)
        LOG.debug("returning %s %s", response.status_code, response.response_data)
        return response
    except Exception as e:
        LOG.exception("something went wrong: %s", e)

class MyBot(BaseDispatch):
    @debounce(30, text=lambda t: t.ts)
    def on_message(self, srv=None, sender=None, channel=None, receivers=None, text=None):
        if text.match("hello") is not None:
                          text=Text("hello, world!"))
