Reference documentation and code samples for the Google Cloud Ai Platform V1 Client class MatchServiceClient.
Service Description: MatchService is a Google managed service for efficient vector similarity search at scale.
This class provides the ability to make remote calls to the backing service through method calls that map to API methods. Sample code to get started:
$matchServiceClient = new MatchServiceClient();
try {
$formattedIndexEndpoint = $matchServiceClient->indexEndpointName('[PROJECT]', '[LOCATION]', '[INDEX_ENDPOINT]');
$response = $matchServiceClient->findNeighbors($formattedIndexEndpoint);
} finally {
$matchServiceClient->close();
}
Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.
This service has a new (beta) implementation. See Google\Cloud\AIPlatform\V1\Client\MatchServiceClient to use the new surface.
Namespace
Google \ Cloud \ AIPlatform \ V1Methods
__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 |
↳ 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 |
↳ 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. |
findNeighbors
Finds the nearest neighbors of each vector within the request.
Parameters | |
---|---|
Name | Description |
indexEndpoint |
string
Required. The name of the index endpoint.
Format:
|
optionalArgs |
array
Optional. |
↳ deployedIndexId |
string
The ID of the DeployedIndex that will serve the request. This request is sent to a specific IndexEndpoint, as per the IndexEndpoint.network. That IndexEndpoint also has IndexEndpoint.deployed_indexes, and each such index has a DeployedIndex.id field. The value of the field below must equal one of the DeployedIndex.id fields of the IndexEndpoint that is being called for this request. |
↳ queries |
Query[]
The list of queries. |
↳ returnFullDatapoint |
bool
If set to true, the full datapoints (including all vector values and restricts) of the nearest neighbors are returned. Note that returning full datapoint will significantly increase the latency and cost of the query. |
↳ retrySettings |
RetrySettings|array
Retry settings to use for this call. Can be a Google\ApiCore\RetrySettings object, or an associative array of retry settings parameters. See the documentation on Google\ApiCore\RetrySettings for example usage. |
