How Redis works

• "In memory db" means that it's literally just a hash map that reads/ updates/ deletes values at run time as they come in

How is this implemented?

1. Create a TCP server bounded to a specific port (and address) and listen for incoming stream
2. convert stream into a string
3. Parse string into tokens
4. Interact with cache through generated tokens to update it
5. return a response to the stream

How to run

zig run main.zig

then interact with database with netcat i.e. nc 127.0.0.1 8080

Common errors:

.ADDRINUSE => return error.AddressInUse, This means the port & IP you've got is being used. You can either:

1. Choose a different port
2. Kill the process running at that port:
   • lsof -i :8080
   • kill 1234 (or whatever the id from above is)
