YDB_DATABASE_ROUTING

YDB_DATABASE_ROUTING Dynamic Config

Runtime routing table for YDB databases. Maps a logical database name (a key in the ydb component's static databases) to another already configured database name. An empty map (default) means no routing.

Enables blue-green database deployments, live cross-cluster migration and operator-driven switchover of a service's database without a restart. Routing is resolved per operation, so already-obtained table clients are redirected as well. Single-hop only (the target is not resolved further).
