excellent blog https://eieio.games/essays/scaling-one-million-checkboxes/

• how would i do it
• go process - 1 million atomic.Bools
  • manipulate it with atomic. so you dont need mutexes.
  • one process holds it all in memory easily - no scaling issue there
• app is read heavy
  • have "frontend" servers
  • they connect to the "master" server and relay updates/writes.
  • keeps the master servers bandwidth from becoming saturated.
• bandwidth costs are an issue
  • use a binary protocol
  • use the MSB of the index of the checkbox to indicate if its checked or not
