arduino – Drive very long ws2812b led strip (80 meter)

I have to drive an 80 meters long rgb strip. 100 leds/m.
What’s the best option?

I read Arduino hasn’t enough ram to drive them all so I was thinking about split the strip in slices and every slice be controlled by a raspberry pi. And having all the raspberries internal clocks synced by an ethernet cable.
