Overview

Ruby Client for Cloud Bigtable API (Alpha)

Cloud Bigtable API: API for reading and writing the contents of Bigtables associated with a cloud project.

Quick Start

In order to use this library, you first need to go through the following steps:

  1. Select or create a Cloud Platform project.
  2. Enable billing for your project.
  3. Enable the Cloud Bigtable API.
  4. Setup Authentication.

Installation

$ gem install google-cloud-bigtable

Next Steps

Enabling Logging

To enable logging for this library, set the logger for the underlying gRPC library. The logger that you set may be a Ruby stdlib Logger as shown below, or a Google::Cloud::Logging::Logger that will write logs to Stackdriver Logging. See grpc/logconfig.rb and the gRPC spec_helper.rb for additional information.

Configuring a Ruby stdlib logger:

require "logger"

module MyLogger
  LOGGER = Logger.new $stderr, level: Logger::WARN
  def logger
    LOGGER
  end
end

# Define a gRPC module-level logger method before grpc/logconfig.rb loads.
module GRPC
  extend MyLogger
end

Class Method Details

.new(credentials: nil, scopes: nil, client_config: nil, timeout: nil, metadata: nil, exception_transformer: nil, lib_name: nil, lib_version: nil) ⇒ Object

Service for reading from and writing to existing Bigtable tables.

Parameters:

  • 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 many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

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

    The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

  • client_config (Hash) (defaults to: nil) —

    A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

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

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

  • metadata (Hash) (defaults to: nil) —

    Default metadata to be sent with each request. This can be overridden on a per call basis.

  • exception_transformer (Proc) (defaults to: nil) —

    An optional proc that intercepts any exceptions raised during an API call to inject custom error handling.
