Types

type ConsulConsistencyModes added in v1.9.25 

type ConsulConsistencyModes int32

These are the same consistency modes offered by Consul. For more information please review https://www.consul.io/api-docs/features/consistency. and https://pkg.go.dev/github.com/hashicorp/consul/api#QueryOptions.

Note: Gloo handles staleness well (as it runs update loops ~ once/second) but makes many requests to get consul endpoints so users may want to opt into stale reads once the implications are understood. 

const (
	// default - Consul HTTP API queries use default mode by default.
	// It is strongly consistent in almost all cases. However, there is a small
	// window in which a new leader may be elected during which the old leader may
	// respond with stale values. The trade-off is fast reads but potentially stale
	// values. The condition resulting in stale reads is hard to trigger, and most
	// clients should not need to worry about this case. Also, note that this race
	// condition only applies to reads, not writes.
	//
	// For more, see https://www.consul.io/api-docs/features/consistency#consul-http-api-queries
	ConsulConsistencyModes_DefaultMode ConsulConsistencyModes = 0
	// AllowStale allows any Consul server (non-leader) to service
	// a read. This allows for lower latency and higher throughput
	//
	// stale - Consul DNS queries use stale mode by default. This mode allows any
	// server to handle the read regardless of whether it is the leader. The trade-off
	// is very fast and scalable reads with a higher likelihood of stale values. Results
	// are generally consistent to within 50 milliseconds of the leader, though there is
	// no upper limit on this staleness. Since this mode allows reads without a leader, a
	// cluster that is unavailable (no quorum) can still respond to queries.
	//
	// Gloo handles staleness well (as it runs update loops ~ once/second) so users may want
	// to opt into this.
	ConsulConsistencyModes_StaleMode ConsulConsistencyModes = 1
	// RequireConsistent forces the read to be fully consistent.
	// This is more expensive but prevents ever performing a stale
	// read.
	//
	// consistent - This mode is strongly consistent without caveats. It requires that a
	// leader verify with a quorum of peers that it is still leader. This introduces an
	// additional round-trip to all server nodes. The trade-off is increased latency due
	// to an extra round trip. Most clients should not use this unless they cannot tolerate
	// a stale read.
	//
	// Gloo handles staleness well (as it runs update loops ~ once/second) so users may want
	// to strongly consider their requirements before enabling this.

Upstream Spec for Consul Upstreams consul Upstreams represent a set of one or more addressable pods for a consul Service the Gloo consul Upstream maps to a single service port. Because consul Services support multiple ports, Gloo requires that a different upstream be created for each port consul Upstreams are typically generated automatically by Gloo from the consul API
