Overview

Configuration class for the DatabaseAdmin API.

This class represents the configuration for DatabaseAdmin, providing control over timeouts, retry behavior, logging, transport parameters, and other low-level controls. Certain parameters can also be applied individually to specific RPCs. See Rpcs for a list of RPCs that can be configured independently.

Configuration can be applied globally to all clients, or to a single client on construction.

Examples:


# Modify the global config, setting the timeout for
# list_databases to 20 seconds,
# and all remaining timeouts to 10 seconds.
::Google::Cloud::Spanner::Admin::Database::V1::DatabaseAdmin::Client.configure do |config|
  config.timeout = 10.0
  config.rpcs.list_databases.timeout = 20.0
end

# Apply the above configuration only to a new client.
client = ::Google::Cloud::Spanner::Admin::Database::V1::DatabaseAdmin::Client.new do |config|
  config.timeout = 10.0
  config.rpcs.list_databases.timeout = 20.0
end
