Shuffle Sharding Benefit

Shuffle sharding improves resilience mainly because it:
Options
  1. 1Assigns each tenant a small random subset of workers so a failing worker affects only an intersection of tenants
  2. 2Replicates every incoming request to all available nodes synchronously before acknowledging it
  3. 3Pins each tenant to a single shared worker so the cache stays warm and locality is preserved
  4. 4Eliminates the need for client retries by guaranteeing that no worker ever fails mid-request
