Google Cloud Data Catalog Lineage V1 Client - Class LineageClient (0.2.1)

Reference documentation and code samples for the Google Cloud Data Catalog Lineage V1 Client class LineageClient.

Service Description: Lineage is used to track data flows between assets over time. You can create LineageEvents to record lineage between multiple sources and a single target, for example, when table data is based on data from multiple tables.

This class is currently experimental and may be subject to changes.

Namespace

Google \ Cloud \ DataCatalog \ Lineage \ V1 \ Client

Methods

__construct

Constructor.

Parameters
Name	Description
`options`	`array` Optional. Options for configuring the service API wrapper.
`↳ apiEndpoint`	`string` The address of the API remote host. May optionally include the port, formatted as "
`↳ credentials`	`string\|array\|FetchAuthTokenInterface\|CredentialsWrapper` The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored.
`↳ credentialsConfig`	`array` Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() .
`↳ disableRetries`	`bool` Determines whether or not retries defined by the client configuration should be disabled. Defaults to `false`.
`↳ clientConfig`	`string\|array` Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder.
`↳ transport`	`string\|TransportInterface` The transport used for executing network requests. May be either the string `rest` or `grpc`. Defaults to `grpc` if gRPC support is detected on the system. Advanced usage: Additionally, it is possible to pass in an already instantiated Google\ApiCore\Transport\TransportInterface object. Note that when this object is provided, any settings in $transportConfig, and any $apiEndpoint setting, will be ignored.
`↳ transportConfig`	`array` Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options.
`↳ clientCertSource`	`callable` A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS.

batchSearchLinkProcesses

Retrieve information about LineageProcesses associated with specific links. LineageProcesses are transformation pipelines that result in data flowing from source to target assets. Links between assets represent this operation.

If you have specific link names, you can use this method to verify which LineageProcesses contribute to creating those links. See the SearchLinks method for more information on how to retrieve link name.

You can retrieve the LineageProcess information in every project where you have the datalineage.events.get permission. The project provided in the URL is used for Billing and Quota.

The async variant is Google\Cloud\DataCatalog\Lineage\V1\Client\BaseClient\self::batchSearchLinkProcessesAsync() .
