Wire protocol compatible so all existing clients work - they don’t need to be shard aware. Includes connection pooler so you can replace PgBouncer et al. Can run multiple routers for HA. Live config reloading. ### Tradeoffs Doesn’t support cross-shard queries. Docs are limited - no quick start guide, but browsing the example configs gives you an idea of how to get going.
