Reference documentation and code samples for the Cloud Bigtable API class Google::Cloud::Bigtable::RoutingPolicy.
RoutingPolicy
An abstract routing policy.
See subclasses for concrete implementations:
- MultiClusterRoutingUseAny - Read/write requests may be routed to any cluster in the instance and will fail over to another cluster in the event of transient errors or delays. Choosing this option sacrifices read-your-writes consistency to improve availability.
- SingleClusterRouting - Unconditionally
routes all read/write requests to a specific cluster. This option
preserves read-your-writes consistency but does not improve
availability. Value contains
cluster_id
and optional fieldallow_transactional_writes
.

Examples
Create an app profile with a single cluster routing policy.
require "google/cloud/bigtable" bigtable = Google::Cloud::Bigtable.new instance = bigtable.instance "my-instance" routing_policy = Google::Cloud::Bigtable::AppProfile.single_cluster_routing( "my-cluster", allow_transactional_writes: true ) app_profile = instance.create_app_profile( "my-app-profile", routing_policy, description: "App profile for user data instance" ) puts app_profile.routing_policy
Create an app profile with multi-cluster routing policy.
require "google/cloud/bigtable" bigtable = Google::Cloud::Bigtable.new instance = bigtable.instance "my-instance" routing_policy = Google::Cloud::Bigtable::AppProfile.multi_cluster_routing app_profile = instance.create_app_profile( "my-app-profile", routing_policy, description: "App profile for user data instance" ) puts app_profile.routing_policy
