Overview

Each RPC normalizes the partition IDs of the keys in its input entities, and always returns entities with keys with normalized partition IDs. This applies to all keys and entities, including those in values, except keys with both an empty path and an empty or unset partition ID. Normalization of input keys sets the project ID (if not already set) to the project ID from the request.

Constructor Details

#initialize(service_path: SERVICE_ADDRESS, port: DEFAULT_SERVICE_PORT, channel: nil, chan_creds: nil, scopes: ALL_SCOPES, client_config: {}, timeout: DEFAULT_TIMEOUT, app_name: nil, app_version: nil, lib_name: nil, lib_version: "") ⇒ DatastoreClient

Returns a new instance of DatastoreClient

Parameters:

  • service_path (String) —

    The domain name of the API remote host.

  • port (Integer) —

    The port on which to connect to the remote host.

  • channel (Channel) —

    A Channel object through which to make calls.

  • chan_creds (Grpc::ChannelCredentials) —

    A ChannelCredentials for the setting up the RPC client.

  • client_config (Hash) —

    A Hash for call options for each method. See Google::Gax#construct_settings for the structure of this data. Falls back to the default config if not specified or the specified config is missing data points.

  • timeout (Numeric) —

    The default timeout, in seconds, for calls made through this client.

#commit(project_id, mode, mutations, transaction: nil, options: nil) ⇒ Google::Datastore::V1::CommitResponse

Commits a transaction, optionally creating, deleting or modifying some entities.

Examples:

require "google/cloud/datastore/v1/datastore_client"

DatastoreClient = Google::Cloud::Datastore::V1::DatastoreClient
Mode = Google::Datastore::V1::CommitRequest::Mode

datastore_client = DatastoreClient.new
project_id = ''
mode = Mode::MODE_UNSPECIFIED
mutations = []
response = datastore_client.commit(project_id, mode, mutations)

Parameters:

  • project_id (String) —

    The ID of the project against which to make the request.

  • mode (Google::Datastore::V1::CommitRequest::Mode) —

    The type of commit to perform. Defaults to +TRANSACTIONAL+.

  • transaction (String) —

    The identifier of the transaction associated with the commit. A transaction identifier is returned by a call to Datastore::BeginTransaction.

  • mutations (Array<Google::Datastore::V1::Mutation>) —

    The mutations to perform.

    When mode is +TRANSACTIONAL+, mutations affecting a single entity are applied in order. The following sequences of mutations affecting a single entity are not permitted in a single +Commit+ request:

    • +insert+ followed by +insert+
    • +update+ followed by +insert+
    • +upsert+ followed by +insert+
    • +delete+ followed by +update+

    When mode is +NON_TRANSACTIONAL+, no two mutations may affect a single entity.

  • options (Google::Gax::CallOptions) —

    Overrides the default settings for this call, e.g, timeout, retries, etc.

Returns:

Raises:

  • (Google::Gax::GaxError) —

    if the RPC is aborted.
