How it works:

1) there’s a compute layer (this can be anything) and a storage layer (a cloudflare durable object instance) 2) you send redis commands to the compute layer using either a) rest b) or upstash sdks (see upstash docs) 3) compute layer translates redis commands to sqlite queries 4) storage layer executes them in a transaction 5)results are returned back to you

post script disclaimer -- this started out as a side project where i was trying to work around fun constriants i made up (serverless, free, etc.). if you try it out and run into problems, bug reports are welcome !!
