Attributes | |
---|---|
Name | Description |
parent |
str
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.types.StructuredQuery
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. This field is a member of oneof _ query_type .
|
partition_count |
int
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 |
str
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 |
int
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_pb2.Timestamp
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. This field is a member of oneof _ consistency_selector .
