## AI overview

Supabase is launching Postgres Read Replicas, which asynchronously copy data from a primary database and serve read-only traffic. Replicas can distribute load, support redundancy and complex queries, and reduce latency by running in regions closer to users. The article also discusses replication lag, scaling limits, recovery complexity, and application changes needed to use replicas effectively.
