Service discovery service architecture overview.

  "cluster": "{...}",
  "refresh_delay_ms": "{...}"
}

cluster

(required, object) A standard definition of an upstream cluster that hosts the service discovery service. The cluster must run a REST service that implements the SDS HTTP API.

refresh_delay_ms

(required, integer) The delay, in milliseconds, between fetches to the SDS API for each configured SDS cluster. Envoy will add an additional random jitter to the delay that is between zero and refresh_delay_ms milliseconds. Thus the longest possible refresh delay is 2 * refresh_delay_ms.
