+### Example (Cassandra — multi-DC)
+
+Use `datacenters` instead of `hosts` when your cluster spans multiple datacenters.
+Each entry gets a named Cassandra **execution profile** keyed by its `name` field,
+enabling per-DC routing. The default profile is determined by `load_balancing.local_dc`
+(or the first datacenter entry when `load_balancing` is absent). Use the optional
+`routing` block to direct reads and writes to specific datacenters. The keyspace must
+already exist; Feast does not create it automatically.
+
+`datacenters` is mutually exclusive with `hosts` and `secure_bundle_path`.
