Methods

.configure

def self.configure() { |config| ... } -> Client::Configuration

Configure the MetadataService Client class.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns
Example 
# Modify the configuration for all MetadataService clients
::Google::Cloud::Dataplex::V1::MetadataService::Client.configure do |config|
  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

Configure the MetadataService Client instance.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on Client.configure.

See Configuration for a description of the configuration fields.

Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns

    • parenthetical grouping: ( )

    Sample filter expression: `?filter="key1 < value1 OR key2 > value2"

    Notes:

    • Keys to the left of operators are case insensitive.
    • Partition results are sorted first by creation time, then by lexicographic order.
    • Up to 20 key value filter pairs are allowed, but due to performance considerations, only the first 10 will be used as a filter.

  • (response, operation) — Access the result along with the RPC operation
