    ) -> (
        google.cloud.aiplatform.matching_engine.matching_engine_index_endpoint.MatchingEngineIndexEndpoint
    )

Deploys an existing index resource to this endpoint resource.

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `index` | `MatchingEngineIndex` Required. The Index this is the deployment of. We may refer to this Index as the DeployedIndex's "original" Index. |
| `deployed_index_id` | `str` Required. The user specified ID of the DeployedIndex. The ID can be up to 128 characters long and must start with a letter and only contain letters, numbers, and underscores. The ID must be unique within the project it is created in. |
| `display_name` | `str` The display name of the DeployedIndex. If not provided upon creation, the Index's display_name is used. |
| `machine_type` | `str` Optional. The type of machine. Not specifying machine type will result in model to be deployed with automatic resources. |
| `min_replica_count` | `int` Optional. The minimum number of machine replicas this deployed model will be always deployed on. If traffic against it increases, it may dynamically be deployed onto more replicas, and as traffic decreases, some of these extra replicas may be freed. If this value is not provided, the value of 2 will be used. |
| `max_replica_count` | `int` Optional. The maximum number of replicas this deployed model may be deployed on when the traffic against it increases. If requested value is too large, the deployment will error, but if deployment succeeds then the ability to scale the model to that many replicas is guaranteed (barring service outages). If traffic against the deployed model increases beyond what its replicas at maximum may handle, a portion of the traffic will be dropped. If this value is not provided, the larger value of min_replica_count or 2 will be used. If value provided is smaller than min_replica_count, it will automatically be increased to be min_replica_count. |
| `enable_access_logging` | `bool` Optional. If true, private endpoint's access logs are sent to StackDriver Logging. These logs are like standard server access logs, containing information like timestamp and latency for each MatchRequest. Note that Stackdriver logs may incur a cost, especially if the deployed index receives a high queries per second rate (QPS). Estimate your costs before enabling this option. |
| `reserved_ip_ranges` | `Sequence[str]` Optional. A list of reserved ip ranges under the VPC network that can be used for this DeployedIndex. If set, we will deploy the index within the provided ip ranges. Otherwise, the index might be deployed to any ip ranges under the provided VPC network. The value sohuld be the name of the address (<https://cloud.google.com/compute/docs/reference/rest/v1/addresses>) Example: 'vertex-ai-ip-range'. |
| `deployment_group` | `str` Optional. The deployment group can be no longer than 64 characters (eg: 'test', 'prod'). If not set, we will use the 'default' deployment group. Creating `deployment_groups` with `reserved_ip_ranges` is a recommended practice when the peered network has multiple peering ranges. This creates your deployments from predictable IP spaces for easier traffic administration. Also, one deployment_group (except 'default') can only be used with the same reserved_ip_ranges which means if the deployment_group has been used with reserved_ip_ranges: \[a, b, c\], using it with \[a, b\] or \[d, e\] is disallowed. Note: we only support up to 5 deployment groups(not including 'default'). |
| `auth_config_audiences` | `Sequence[str]` The list of JWT `audiences https://tools.ietf.org/html/draft-ietf-oauth-json-web-token-32#section-4.1.3`__. that are allowed to access. A JWT containing any of these audiences will be accepted. auth_config_audiences and auth_config_allowed_issuers must be passed together. |
| `auth_config_allowed_issuers` | `Sequence[str]` A list of allowed JWT issuers. Each entry must be a valid Google service account, in the following format: `service-account-name@project-id.iam.gserviceaccount.com` auth_config_audiences and auth_config_allowed_issuers must be passed together. |
| `request_metadata` | `Sequence[Tuple[str, str]]` Optional. Strings which should be sent along with the request as metadata. |
| `sync` | `bool` Whether to execute this method synchronously. If False, this method will be executed in a concurrent Future and any downstream object will be immediately returned and synced when the Future has completed. |
| `deploy_request_timeout` | `float` Optional. The timeout for the request in seconds. |
| `psc_automation_configs` | `Sequence[Tuple[str, str]]` Optional. A list of (project_id, network) pairs for Private Service Connection endpoints to be setup for the deployed index. The project_id is the project number of the project that the network is in, and network is the name of the network. Network is the full name of the Google Compute Engine `network https://cloud.google.com/compute/docs/networks-and-firewalls#networks`__ to which the index should be deployed to. Format:{projects/{project}/global/networks/{network}. Where {project} is a project number, as in '12345', and {network} is network name. For example: \[(project_id_1, network_1), (project_id_1, network_2))\] will enable PSC automation for the index to be deployed to project_id_1's network_1 and network_2 and can be queried within these networks. |
| `deployment_tier` | `str` Optional. The deployment tier that the index is deployed to. |

Please refer to <https://cloud.google.com/vertex-ai/docs/matching-engine/filtering#json> for more detail. |
| `per_crowding_attribute_neighbor_count` | `int` Optional. Crowding is a constraint on a neighbor list produced by nearest neighbor search requiring that no more than some value k' of the k neighbors returned have the same value of crowding_attribute.

For hybrid queries, each query is a hybrid query of type aiplatform.matching_engine.matching_engine_index_endpoint.HybridQuery. |
| `num_neighbors` | `int` Required. The number of nearest neighbors to be retrieved from database for each query. |
| `filter` | `List[Namespace]` Optional. A list of Namespaces for filtering the matching results. For example, \[Namespace("color", \["red"\], \[\]), Namespace("shape", \[\], \["squared"\])\] will match datapoints that satisfy "red color" but not include datapoints with "squared shape". Please refer to <https://cloud.google.com/vertex-ai/docs/matching-engine/filtering#json> for more detail. |
| `per_crowding_attribute_num_neighbors` | `int` Optional. Crowding is a constraint on a neighbor list produced by nearest neighbor search requiring that no more than some value k' of the k neighbors returned have the same value of crowding_attribute. It's used for improving result diversity. This field is the maximum number of matches with the same crowding tag. |
| `approx_num_neighbors` | `int` The number of neighbors to find via approximate search before exact reordering is performed. If not set, the default value from scam config is used; if set, this value must be \> 0. |
| `fraction_leaf_nodes_to_search_override` | `float` Optional. The fraction of the number of leaves to search, set at query time allows user to tune search performance. This value increase result in both search accuracy and latency increase. The value should be between 0.0 and 1.0. |
| `low_level_batch_size` | `int` Optional. Selects the optimal batch size to use for low-level batching. Queries within each low level batch are executed sequentially while low level batches are executed in parallel. This field is optional, defaults to 0 if not set. A non-positive number disables low level batching, i.e. all queries are executed sequentially. |
| `numeric_filter` | `Optional[list[NumericNamespace]]` Optional. A list of NumericNamespaces for filtering the matching results. For example: \[NumericNamespace(name="cost", value_int=5, op="GREATER")\] will match datapoints that its cost is greater than 5. |
| `signed_jwt` | `str` Optional. A signed JWT for accessing the private endpoint. |
| `psc_network` | `Optional[str]` Optional. Required for private service automation enabled deployed index. This network is the PSC network the match query is executed in. This (project, network) pair must already be specified for psc automation when the index is deployed. The format is `projects/{project_id}/global/networks/{network_name}`. An alternative is to set the `private_service_connect_ip_address` field for this MatchingEngineIndexEndpoint instance, if the ip address is already known. |

### mutate_deployed_index

    mutate_deployed_index(
        deployed_index_id: str,
        min_replica_count: int = 1,
        max_replica_count: int = 1,
        request_metadata: typing.Optional[typing.Sequence[typing.Tuple[str, str]]] = (),
        mutate_request_timeout: typing.Optional[float] = None,
    )

Updates an existing deployed index under this endpoint resource.

| **Parameters** ||
|---|---|
| **Name** | **Description** |
| `index_id` | `str` Required. The ID of the MatchingEnginIndex associated with the DeployedIndex. |
| `deployed_index_id` | `str` Required. The user specified ID of the DeployedIndex. The ID can be up to 128 characters long and must start with a letter and only contain letters, numbers, and underscores. The ID must be unique within the project it is created in. |
| `min_replica_count` | `int` Optional. The minimum number of machine replicas this deployed model will be always deployed on. If traffic against it increases, it may dynamically be deployed onto more replicas, and as traffic decreases, some of these extra replicas may be freed. |
| `max_replica_count` | `int` Optional. The maximum number of replicas this deployed model may be deployed on when the traffic against it increases. If requested value is too large, the deployment will error, but if deployment succeeds then the ability to scale the model to that many replicas is guaranteed (barring service outages). If traffic against the deployed model increases beyond what its replicas at maximum may handle, a portion of the traffic will be dropped. If this value is not provided, the larger value of min_replica_count or 1 will be used. If value provided is smaller than min_replica_count, it will automatically be increased to be min_replica_count. |
| `request_metadata` | `Sequence[Tuple[str, str]]` Optional. Strings which should be sent along with the request as metadata. |
| `timeout` | `float` Optional. The timeout for the request in seconds. |

### read_index_datapoints
