FalconUp 2026 - redis

! clarification

milestone2 is data sources, milestone3 is database schema and stuff

right now data is being saved nowhere (live api calls + cache)

redis

use redis for cache instead of writing your own cache from scratch

Redis: caching python library

• key-value store that lives outside of app
• survives server restarts and can be shared across multiple instances

# Store a value (with expiration)

r.set("some_key", some_bytes, ex=60)   # ex=60 means expires in 60 seconds

# Retrieve a value

data = r.get("some_key")            # returns bytes, or None if expired/missing

# Delete a value

r.delete("some_key")

Pickle: python library

use alongside Redis

→ redis stores data in bytes

→ pickle converts bytes back into objects

pickle.dumps(value) — converts your Python object into bytes before storing

pickle.loads(data) — converts bytes back into a Python object after retrieving

TTL: time to live (cache terminology)

how many seconds until cache value thrown away

redis tests use fakeredis package lol

trying out running redis

it all works!

now to install redis on the oc40 server:

first update apt:

sudo apt update

install redis

sudo apt install redis-server -y

config redis

sudo nano /etc/redis/redis.conf file

bind 127.0.0.1 -::1

-- change to -->

bind 127.0.0.1 172.17.0.1

## tells redis to use docker ip

protected-mode yes

-- change to -->

protected-mode no

## allows non localhost ips to work

enable redis:

sudo systemctl enable redis-server

restart it:

sudo systemctl restart redis-server

test:

ubuntu@oc40:~$ redis-cli ping
PONG

nice!!

make a quick frontend ui

nice!! 🎉
