Modules: Bigtable

Class Method Summary

• .bigtable(project_id: nil, credentials: nil, scope: nil, timeout: nil) ⇒ Google::Cloud::Bigtable::Project

  Creates a Cloud Bigtable client instance for data, table admin and instance admin operations.

Instance Method Summary

• #bigtable(scope: nil, timeout: nil, credentials: nil) ⇒ Google::Cloud::Bigtable::Project

  Creates a new object for connecting to the Cloud Bigtable service.

Class Method Details

.bigtable(project_id: nil, credentials: nil, scope: nil, timeout: nil) ⇒ Google::Cloud::Bigtable::Project

Creates a Cloud Bigtable client instance for data, table admin and instance admin operations.

Examples:

require "google/cloud/bigtable"

bigtable = Google::Cloud.bigtable

Parameters:

• project_id (String) (defaults to: nil) —

  Project identifier for the Bigtable service you are connecting to. If not present, the default project for the credentials is used.

• credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) (defaults to: nil) —

  The means for authenticating requests made by the client. This parameter can be one of the following types. Google::Auth::Credentials uses the properties of its represented keyfile for authenticating requests made by this client. String will be treated as the path to the keyfile to use to construct credentials for this client. Hash will be treated as the contents of a keyfile to use to construct credentials for this client. GRPC::Core::Channel will be used to make calls through. GRPC::Core::ChannelCredentials will be used to set up the gRPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. Proc will be used as an updater_proc for the gRPC channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

• scope (Array<String>) (defaults to: nil) —

  The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs. The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

• timeout (Integer) (defaults to: nil) —

  The default timeout, in seconds, for calls made through this client.

Returns:

• (Google::Cloud::Bigtable::Project)

# File 'lib/google-cloud-bigtable.rb', line 116

def self.bigtable project_id: nil, credentials: nil, scope: nil, timeout: nil
  require "google/cloud/bigtable"
  Google::Cloud::Bigtable.new(
    project_id:  project_id,
    credentials: credentials,
    scope:       scope,
    timeout:     timeout
  )
end

Instance Method Details

#bigtable(scope: nil, timeout: nil, credentials: nil) ⇒ Google::Cloud::Bigtable::Project

Creates a new object for connecting to the Cloud Bigtable service.

For more information on connecting to Google Cloud Platform, see the Authentication Guide.

Examples:

require "google/cloud/bigtable"

gcloud  = Google::Cloud.new

bigtable = gcloud.bigtable

Parameters:

• scope (Array<String>) (defaults to: nil) —

  The OAuth 2.0 scopes controlling the set of resources and operations that the connection can access. See Using OAuth 2.0 to Access Google APIs. The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

• timeout (Integer) (defaults to: nil) —

  The default timeout, in seconds, for calls made through this client.

• credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) (defaults to: nil) —

  Provides the means for authenticating requests made by the client. This parameter can be one of the following types. Google::Auth::Credentials uses the properties of its represented keyfile for authenticating requests made by this client. String will be treated as the path to the keyfile to use to construct credentials for this client. Hash will be treated as the contents of a keyfile to use to construct credentials for this client. GRPC::Core::Channel will be used to make calls through. GRPC::Core::ChannelCredentials will be used to set up the gRPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. Proc will be used as an updater_proc for the gRPC channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

Returns:

• (Google::Cloud::Bigtable::Project)
