google-cloud-bigtable - Class Google::Cloud::Bigtable::RoutingPolicy (v2.6.5)

Reference documentation and code samples for the google-cloud-bigtable 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 field allow_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
