Cloud Bigtable API - Class Google::Cloud::Bigtable::Table::ClusterState (v2.12.1)

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

Table::ClusterState is the state of a table's data in a particular cluster.

Inherits

  • Object

Example

Retrieve a table with cluster states.

require "google/cloud/bigtable"

bigtable = Google::Cloud::Bigtable.new

table = bigtable.table "my-instance", "my-table", view: :FULL, perform_lookup: true

table.cluster_states.each do |cs|
  puts cs.cluster_name
  puts cs.replication_state
  puts cs.encryption_infos.first.encryption_type
end

Methods

#cluster_name

def cluster_name() -> String

The name of the cluster.

Returns
  • (String) — the current value of cluster_name

#cluster_name=

def cluster_name=(value) -> String

The name of the cluster.

Parameter
  • value (String) — the newly set value
Returns
  • (String) — the newly set value

#encryption_infos

def encryption_infos() -> Array<Google::Cloud::Bigtable::EncryptionInfo>

The encryption info value objects for the table in this cluster. The encryption info is only present when the table view is ENCRYPTION_VIEW or FULL. See also Instance::ClusterMap#add.

Returns

#initializing?

def initializing?() -> Boolean

The cluster was recently created, and the table must finish copying over pre-existing data from other clusters before it can begin receiving live replication updates and serving.

Returns

#planned_maintenance?

def planned_maintenance?() -> Boolean

The table is temporarily unable to serve requests from this cluster due to planned internal maintenance.

Returns
  • (Boolean) — true if the value of #replication_state is PLANNED_MAINTENANCE, false otherwise.

#ready?

def ready?() -> Boolean

The table can serve requests from this cluster. Depending on replication delay, reads may not immediately reflect the state of the table in other clusters.

Returns

#ready_optimizing?

def ready_optimizing?() -> Boolean

The table is fully created and ready for use after a restore, and is being optimized for performance. When optimizations are complete, the table will transition to READY state.

Returns
  • (Boolean) — true if the value of #replication_state is READY_OPTIMIZING, false otherwise.

#replication_state

def replication_state() -> Symbol

The state of replication for the table in this cluster. Valid values include:

  • :INITIALIZING - The cluster was recently created.
  • :PLANNED_MAINTENANCE - The table is temporarily unable to serve.
  • :UNPLANNED_MAINTENANCE - The table is temporarily unable to serve.
  • :READY - The table can serve.
  • :READY_OPTIMIZING - The table is fully created and ready for use after a restore, and is being optimized for performance. When optimizations are complete, the table will transition to READY state.
  • :STATE_NOT_KNOWN - If replication state is not present in the object because the table view is not REPLICATION_VIEW or FULL.
  • :UNKNOWN - If it could not be determined whether or not the table has data in a particular cluster (for example, if its zone is unavailable.)
Returns
  • (Symbol) — The state of replication.

#unplanned_maintenance?

def unplanned_maintenance?() -> Boolean

The table is temporarily unable to serve requests from this cluster due to unplanned or emergency maintenance.

Returns
  • (Boolean) — true if the value of #replication_state is UNPLANNED_MAINTENANCE, false otherwise.
