Cloud Bigtable API - Class Google::Cloud::Bigtable::SingleClusterRouting (v2.11.0)

Reference documentation and code samples for the Cloud Bigtable API class Google::Cloud::Bigtable::SingleClusterRouting.

A single-cluster routing policy for all read/write requests that use the associated app profile.

Unconditionally routes all read/write requests to a specific cluster. This option preserves read-your-writes consistency, but does not improve availability.

Inherits

Example

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

Methods

#allow_transactional_writes

def allow_transactional_writes() -> true, false
Returns
  • (true, false) — If true, CheckAndMutateRow and ReadModifyWriteRow requests are allowed by this app profile. It is unsafe to send these requests to the same table/row/column in multiple clusters. Default value is false.

#allow_transactional_writes=

def allow_transactional_writes=(value) -> true, false
Parameter
  • value (true, false) — If true, CheckAndMutateRow and ReadModifyWriteRow requests are allowed by this app profile. It is unsafe to send these requests to the same table/row/column in multiple clusters. Default value is false.
Returns
  • (true, false) — If true, CheckAndMutateRow and ReadModifyWriteRow requests are allowed by this app profile. It is unsafe to send these requests to the same table/row/column in multiple clusters. Default value is false.

#cluster_id

def cluster_id() -> String
Returns
  • (String) — The cluster to which read/write requests should be routed.

#cluster_id=

def cluster_id=(value) -> String
Parameter
  • value (String) — The cluster to which read/write requests should be routed.
Returns
  • (String) — The cluster to which read/write requests should be routed.

#initialize

def initialize(cluster_id, allow_transactional_writes) -> SingleClusterRouting

Creates a new single-cluster routing policy.

Parameters
  • cluster_id (String) — The cluster to which read/write requests should be routed.
  • allow_transactional_writes (Boolean) — If true, CheckAndMutateRow and ReadModifyWriteRow requests are allowed by this app profile. It is unsafe to send these requests to the same table/row/column in multiple clusters. Default value is false.
Returns
