#batch_get_documents

def batch_get_documents(request, options = nil) -> ::Enumerable<::Google::Cloud::Firestore::V1::BatchGetDocumentsResponse>
def batch_get_documents(database: nil, documents: nil, mask: nil, transaction: nil, new_transaction: nil, read_time: nil) -> ::Enumerable<::Google::Cloud::Firestore::V1::BatchGetDocumentsResponse>

Gets multiple documents.

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

Overloads 
def batch_get_documents(request, options = nil) -> ::Enumerable<::Google::Cloud::Firestore::V1::BatchGetDocumentsResponse>
Pass arguments to batch_get_documents via a request object, either of type BatchGetDocumentsRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Firestore::V1::BatchGetDocumentsRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
def batch_get_documents(database: nil, documents: nil, mask: nil, transaction: nil, new_transaction: nil, read_time: nil) -> ::Enumerable<::Google::Cloud::Firestore::V1::BatchGetDocumentsResponse>
Pass arguments to batch_get_documents via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • database (::String) — Required. The database name. In the format: projects/{project_id}/databases/{database_id}.
  • 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::Cloud::Firestore::V1::DocumentMask, ::Hash) — 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.

  • transaction (::String) — Reads documents in a transaction.
  • new_transaction (::Google::Cloud::Firestore::V1::TransactionOptions, ::Hash) — 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.
  • read_time (::Google::Protobuf::Timestamp, ::Hash) — Reads documents as they were at the given time.

    This must be a microsecond precision timestamp within the past one hour, or if Point-in-Time Recovery is enabled, can additionally be a whole minute timestamp within the past 7 days.

Returns
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.
Example

Basic example

require "google/cloud/firestore/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Firestore::V1::Firestore::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Firestore::V1::BatchGetDocumentsRequest.new

# Call the batch_get_documents method to start streaming.

def batch_write(database: nil, writes: nil, labels: nil) -> ::Google::Cloud::Firestore::V1::BatchWriteResponse

Applies a batch of write operations.

The BatchWrite method does not apply the write operations atomically and can apply them out of order. Method does not allow more than one write per document. Each write succeeds or fails independently. See the BatchWriteResponse for the success status of each write.

If you require an atomically applied set of writes, use Commit instead.

  • labels (::Hash{::String => ::String}) — Labels associated with this batch write.
Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
Returns
Raises

  • collection_id (::String) — Optional. The collection ID, relative to parent, to list.

    For example: chatrooms or messages.

    This is optional, and when not provided, Firestore will list documents from all collections under the provided parent.

  • page_size (::Integer) — Optional. The maximum number of documents to return in a single response.

    Firestore may return fewer than this value.

  • page_token (::String) — Optional. A page token, received from a previous ListDocuments response.

  • order_by (::String) — Optional. The optional ordering of the documents to return.

    For example: priority desc, __name__ desc.

    This mirrors the ORDER BY used in Firestore queries but in a string representation. When absent, documents are ordered based on __name__ ASC.

  • show_missing (::Boolean) — If the list should show missing documents.

    A document is missing if it does not exist, but there are sub-documents nested underneath it. When true, such missing documents will be returned with a key but will not have fields, create_time, or update_time set.

    Requests with show_missing may not specify where or order_by.

Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
Returns
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.
Example

client = Google::Cloud::Firestore::V1::Firestore::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Firestore::V1::ListDocumentsRequest.new

# Call the list_documents method.
result = client.list_documents request

# The returned object is of type Gapic::PagedEnumerable. You can iterate
# over elements, and API calls will be issued to fetch pages as needed.

  # Each element is of type ::Google::Cloud::Firestore::V1::Document.
  p item
end

#location_client

def location_client() -> Google::Cloud::Location::Locations::Rest::Client

#partition_query

def partition_query(request, options = nil) -> ::Gapic::Rest::PagedEnumerable<::Google::Cloud::Firestore::V1::Cursor>
def partition_query(parent: nil, structured_query: nil, partition_count: nil, page_token: nil, page_size: nil, read_time: nil) -> ::Gapic::Rest::PagedEnumerable<::Google::Cloud::Firestore::V1::Cursor>

Partitions a query by returning partition cursors that can be used to run the query in parallel. The returned partition cursors are split points that can be used by RunQuery as starting/end points for the query results.

Overloads 
def partition_query(request, options = nil) -> ::Gapic::Rest::PagedEnumerable<::Google::Cloud::Firestore::V1::Cursor>
Pass arguments to partition_query via a request object, either of type PartitionQueryRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::Firestore::V1::PartitionQueryRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
def partition_query(parent: nil, structured_query: nil, partition_count: nil, page_token: nil, page_size: nil, read_time: nil) -> ::Gapic::Rest::PagedEnumerable<::Google::Cloud::Firestore::V1::Cursor>
Pass arguments to partition_query via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • parent (::String) — Required. The parent resource name. In the format: projects/{project_id}/databases/{database_id}/documents. Document resource names are not supported; only database resource names can be specified.
  • structured_query (::Google::Cloud::Firestore::V1::StructuredQuery, ::Hash) — A structured query. Query must specify collection with all descendants and be ordered by name ascending. Other filters, order bys, limits, offsets, and start/end cursors are not supported.
  • partition_count (::Integer) — The desired maximum number of partition points. The partitions may be returned across multiple pages of results. The number must be positive. The actual number of partitions returned may be fewer.

    For example, this may be set to one fewer than the number of parallel queries to be run, or in running a data pipeline job, one fewer than the number of workers or compute instances available.

  • page_token (::String) — The next_page_token value returned from a previous call to PartitionQuery that may be used to get an additional set of results. There are no ordering guarantees between sets of results. Thus, using multiple sets of results will require merging the different result sets.

    For example, two subsequent calls using a page_token may return:

    • cursor B, cursor M, cursor Q
    • cursor A, cursor U, cursor W

    To obtain a complete result set ordered with respect to the results of the query supplied to PartitionQuery, the results sets should be merged: cursor A, cursor B, cursor M, cursor Q, cursor U, cursor W

  • page_size (::Integer) — The maximum number of partitions to return in this call, subject to partition_count.

    For example, if partition_count = 10 and page_size = 8, the first call to PartitionQuery will return up to 8 partitions and a next_page_token if more results exist. A second call to PartitionQuery will return up to 2 partitions, to complete the total of 10 specified in partition_count.

  • read_time (::Google::Protobuf::Timestamp, ::Hash) — Reads documents as they were at the given time.

    This must be a microsecond precision timestamp within the past one hour, or if Point-in-Time Recovery is enabled, can additionally be a whole minute timestamp within the past 7 days.

Yields
  • (result, operation) — Access the result along with the TransportOperation object
Yield Parameters
Returns
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.

def run_aggregation_query(parent: nil, structured_aggregation_query: nil, transaction: nil, new_transaction: nil, read_time: nil) -> ::Enumerable<::Google::Cloud::Firestore::V1::RunAggregationQueryResponse>

Runs an aggregation query.

Rather than producing Document results like Firestore.RunQuery, this API allows running an aggregation to produce a series of AggregationResult server-side.

High-Level Example:

-- Return the number of documents in table given a filter. SELECT COUNT(*) FROM ( SELECT * FROM k where a = true );

Overloads 
def run_aggregation_query(request, options = nil) -> ::Enumerable<::Google::Cloud::Firestore::V1::RunAggregationQueryResponse>

  • request (::Google::Cloud::Firestore::V1::RunAggregationQueryRequest, ::Hash) — A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.
  • options (::Gapic::CallOptions, ::Hash) — Overrides the default settings for this call, e.g, timeout, retries etc. Optional. 
def run_aggregation_query(parent: nil, structured_aggregation_query: nil, transaction: nil, new_transaction: nil, read_time: nil) -> ::Enumerable<::Google::Cloud::Firestore::V1::RunAggregationQueryResponse>
Pass arguments to run_aggregation_query via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).
Parameters
  • parent (::String) — Required. The parent resource name. In the format: projects/{project_id}/databases/{database_id}/documents or projects/{project_id}/databases/{database_id}/documents/{document_path}. For example: projects/my-project/databases/my-database/documents or projects/my-project/databases/my-database/documents/chatrooms/my-chatroom
  • structured_aggregation_query (::Google::Cloud::Firestore::V1::StructuredAggregationQuery, ::Hash) — An aggregation query.
  • transaction (::String) — Run the aggregation within an already active transaction.

    The value here is the opaque transaction ID to execute the query in.

  • new_transaction (::Google::Cloud::Firestore::V1::TransactionOptions, ::Hash) — Starts a new transaction as part of the query, defaulting to read-only.

    The new transaction ID will be returned as the first response in the stream.

  • read_time (::Google::Protobuf::Timestamp, ::Hash) — Executes the query at the given timestamp.

    This must be a microsecond precision timestamp within the past one hour, or if Point-in-Time Recovery is enabled, can additionally be a whole minute timestamp within the past 7 days.

Returns
Raises
  • (::Google::Cloud::Error) — if the REST call is aborted.
