Zone-aware replication for live-stores
Zone awareness is a feature that ensures data is replicated across failure domains (which we refer to as “zones”) to provide greater reliability. A failure domain is whatever you define it to be, but commonly may be an availability zone, data center, or server rack.
When zone awareness is set up for live-stores, each Tempo partition is owned by one live-store per zone. This means that if a live-store in one zone becomes unavailable, the live-store in the other zone can continue serving queries for that partition. While data is replicated across zones (RF2), the read quorum is 1. The queriers only need a response from one live-store per partition. This provides high availability without requiring data deduplication on the read path.
