Defined in:

Overview

The Cloud Firestore service.

This service exposes several types of comparable timestamps:

• +create_time+ - The time at which a document was created. Changes only when a document is deleted, then re-created. Increases in a strict monotonic fashion.
• +update_time+ - The time at which a document was last updated. Changes every time a document is modified. Does not change when a write results in no modifications. Increases in a strict monotonic fashion.
• +read_time+ - The time at which a particular state was observed. Used to denote a consistent snapshot of the database or the time at which a Document was observed to not exist.
• +commit_time+ - The time at which the writes in a transaction were committed. Any read with an equal or greater +read_time+ is guaranteed to see the effects of the transaction.

Constructor Details

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

Returns a new instance of FirestoreClient.

Parameters:

• credentials (Google::Auth::Credentials, String, Hash, GRPC::Core::Channel, GRPC::Core::ChannelCredentials, Proc) (defaults to: nil) —

  Provides the means for authenticating requests made by the client. This parameter can be many types. A Google::Auth::Credentials uses a the properties of its represented keyfile for authenticating requests made by this client. A String will be treated as the path to the keyfile to be used for the construction of credentials for this client. A Hash will be treated as the contents of a keyfile to be used for the construction of credentials for this client. A GRPC::Core::Channel will be used to make calls through. A GRPC::Core::ChannelCredentials for the setting up the RPC client. The channel credentials should already be composed with a GRPC::Core::CallCredentials object. A Proc will be used as an updater_proc for the Grpc channel. The proc transforms the metadata for requests, generally, to give OAuth credentials.

• scopes (Array<String>) (defaults to: ALL_SCOPES) —

  The OAuth scopes for this service. This parameter is ignored if an updater_proc is supplied.

• client_config (Hash) (defaults to: {}) —

  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) (defaults to: DEFAULT_TIMEOUT) —

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

#batch_get_documents(database, documents, mask: nil, transaction: nil, new_transaction: nil, read_time: nil, options: nil) ⇒ Enumerable<Google::Firestore::V1beta1::BatchGetDocumentsResponse>

Gets multiple documents.

Documents returned by this method are not guaranteed to be returned in the same order that they were requested.

Examples:

require "google/cloud/firestore/v1beta1"

• documents (Array<String>) —

  The names of the documents to retrieve. In the format: +projects/project_id/databases/database_id/documents/document_path+. The request will fail if any of the document is not a child resource of the given +database+. Duplicate names will be elided.

• mask (Google::Firestore::V1beta1::DocumentMask | Hash) (defaults to: nil) —

  The fields to return. If not set, returns all fields.

  If a document has a field that is not present in this mask, that field will not be returned in the response. A hash of the same form as Google::Firestore::V1beta1::DocumentMask can also be provided.

• transaction (String) (defaults to: nil) —

  Reads documents in a transaction.

• new_transaction (Google::Firestore::V1beta1::TransactionOptions | Hash) (defaults to: nil) —

  Starts a new transaction and reads the documents. Defaults to a read-only transaction. The new transaction ID will be returned as the first response in the stream. A hash of the same form as Google::Firestore::V1beta1::TransactionOptions can also be provided.

• read_time (Google::Protobuf::Timestamp | Hash) (defaults to: nil) —

  Reads documents as they were at the given time. This may not be older than 60 seconds. A hash of the same form as Google::Protobuf::Timestamp can also be provided.

• options (Google::Gax::CallOptions) (defaults to: nil) —

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

Returns:

• (Enumerable<Google::Firestore::V1beta1::BatchGetDocumentsResponse>) —

#write(reqs, options: nil) ⇒ Enumerable<Google::Firestore::V1beta1::WriteResponse>

Note:

EXPERIMENTAL: Streaming requests are still undergoing review. This method interface might change in the future.

Streams batches of document updates and deletes, in order.

Examples:

require "google/cloud/firestore/v1beta1"

firestore_client = Google::Cloud::Firestore::V1beta1.new
formatted_database = Google::Cloud::Firestore::V1beta1::FirestoreClient.database_root_path("[PROJECT]", "[DATABASE]")
request = { database: formatted_database }
requests = [request]
firestore_client.write(requests).each do |element|
  # Process element.
end

Parameters:

• reqs (Enumerable<Google::Firestore::V1beta1::WriteRequest>) —

  The input requests.

• options (Google::Gax::CallOptions) (defaults to: nil) —

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

Returns:

• (Enumerable<Google::Firestore::V1beta1::WriteResponse>) —

  An enumerable of Google::Firestore::V1beta1::WriteResponse instances.

Raises:

• (Google::Gax::GaxError) —

  if the RPC is aborted.
