AggregationQuery(nested_query)

Represents an aggregation query to the Firestore API.

Methods

get

get(transaction=None, retry: Union[retries.Retry, None, gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: float | None = None)

Runs the aggregation query.

This sends a RunAggregationQuery RPC and returns a list of aggregation results in the stream of RunAggregationQueryResponse messages.

Parameters

Name	Description
retry	google.api_core.retry.Retry Designation of what errors, if any, should be retried. Defaults to a system-specified policy.
timeout	float The timeout for this request. Defaults to a system-specified value.

Returns

Type	Description
list	The aggregation query results

stream

stream(transaction=None, retry: Union[retries.Retry, None, gapic_v1.method._MethodDefault] = <_MethodDefault._DEFAULT_VALUE: <object object>>, timeout: float | None = None)

Runs the aggregation query.

This sends a RunAggregationQuery RPC and then returns an iterator which consumes each document returned in the stream of RunAggregationQueryResponse messages.

If a transaction is used and it already has write operations added, this method cannot be used (i.e. read-after-write is not allowed).

Parameters

Name	Description
retry	google.api_core.retry.Retry Designation of what errors, if any, should be retried. Defaults to a system-specified policy.
timeout	float :Yields: AggregationResult -- The result of aggregations of this query The timeout for this request. Defaults to a system-specified value.
