State sync can greatly speed up the time it takes to bring a node online, and the smaller state size will make processing the epoch much faster. There is however a bug that affects osmosisd v5.0.0-v6.0.1 which causes the replay to fail after syncing
This walks through the steps to bring up a new node using state sync on osmosis v6.0.1, this will likely be outdated pretty quickly (Jan 2, 2022) once the bug is fixed.

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.
