34. Make Redis do your work
● Simplifies & minimises BL code
● Consolidates code across platforms
● Minimizes network hops
● Simplifies move to concurrent processing
● Enables custom C code as a service
● Moves compute closer to data (CS 101 pro tip)

35. Make Redis speak
your language
use case #1

43. Make Redis speak your language
for scanned_components in r.hscan_iter(“Royal Starship”, match=”*power*”):
for component in scanned_components:
if component[1].get(“status”) != “ok”:
bypass(component[0]) # <- usually main power drive fail
if shield.is_up():
return
r.execute_command(“r2_droids.fix_shield_generator”)

● Enhances code maintainability by simplifying BL code
● Code consolidation across platforms
● Minimizes network hops

46. But it’s so hard to write!
