class google.cloud.firestore_v1.types.BitSequence(mapping=None, *, ignore_unknown_fields=False, **kwargs)
Bases: proto.message.Message
A sequence of bits, encoded in a byte array.
Each byte in the bitmap
byte array stores 8 bits of the
sequence. The only exception is the last byte, which may store 8 or
fewer bits. The padding
defines the number of bits of the last
byte to be ignored as “padding”. The values of these “padding” bits
are unspecified and must be ignored.
To retrieve the first bit, bit 0, calculate:
(bitmap[0] & 0x01) != 0
. To retrieve the second bit, bit 1,
calculate: (bitmap[0] & 0x02) != 0
. To retrieve the third bit,
bit 2, calculate: (bitmap[0] & 0x04) != 0
. To retrieve the
fourth bit, bit 3, calculate: (bitmap[0] & 0x08) != 0
. To
retrieve bit n, calculate:
(bitmap[n / 8] & (0x01 << (n % 8))) != 0
.
The “size” of a BitSequence
(the number of bits it contains) is
calculated by this formula: (bitmap.length \* 8) - padding
.
bitmap()
The bytes that encode the bit sequence. May have a length of zero.
Type
padding()
The number of bits of the last byte in bitmap
to ignore
as “padding”. If the length of bitmap
is zero, then this
value must be 0
. Otherwise, this value must be between 0
and 7, inclusive.
Type
class google.cloud.firestore_v1.types.BloomFilter(mapping=None, *, ignore_unknown_fields=False, **kwargs)
Bases: proto.message.Message
A bloom filter (https://en.wikipedia.org/wiki/Bloom_filter).
The bloom filter hashes the entries with MD5 and treats the resulting 128-bit hash as 2 distinct 64-bit hash values, interpreted as unsigned integers using 2’s complement encoding.
These two hash values, named h1
and h2
, are then used to
compute the hash_count
hash values using the formula, starting
at i=0
:
h(i) = h1 + (i * h2)
These resulting values are then taken modulo the number of bits in the bloom filter to get the bits of the bloom filter to test for the given entry.

Within a field path, a quoted field name starts and ends
with \`` and may contain any character. Some
characters, including
`, must be escaped using a
\. For example,
`x&y`represents
x&yand
`bak`tik`represents
bak`tik`.

increment()
Adds the given value to the field’s current value. This must be an integer or a double value. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the given value. If either of the given value or the current field value are doubles, both values will be interpreted as doubles. Double arithmetic and representation of double values follow IEEE 754 semantics. If there is positive/negative integer overflow, the field is resolved to the largest magnitude positive/negative integer.
This field is a member of oneof transform_type
.

maximum()
Sets the field to the maximum of its current value and the given value. This must be an integer or a double value. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the given value. If a maximum operation is applied where the field and the input value are of mixed types (that is - one is an integer and one is a double) the field takes on the type of the larger operand. If the operands are equivalent (e.g. 3 and 3.0), the field does not change. 0, 0.0, and -0.0 are all zero. The maximum of a zero stored value and zero input value is always the stored value. The maximum of any numeric value x and NaN is NaN.
This field is a member of oneof transform_type
.
Type
google.cloud.firestore_v1.types.Value
minimum()
Sets the field to the minimum of its current value and the given value. This must be an integer or a double value. If the field is not an integer or double, or if the field does not yet exist, the transformation will set the field to the input value. If a minimum operation is applied where the field and the input value are of mixed types (that is - one is an integer and one is a double) the field takes on the type of the smaller operand. If the operands are equivalent (e.g. 3 and 3.0), the field does not change. 0, 0.0, and -0.0 are all zero. The minimum of a zero stored value and zero input value is always the stored value. The minimum of any numeric value x and NaN is NaN.
This field is a member of oneof transform_type
.
Type
google.cloud.firestore_v1.types.Value
append_missing_elements()
Append the given elements in order if they are not already present in the current field value. If the field is not an array, or if the field does not yet exist, it is first set to the empty array.
Equivalent numbers of different types (e.g. 3L and 3.0) are considered equal when checking if a value is missing. NaN is equal to NaN, and Null is equal to Null. If the input contains multiple equivalent values, only the first will be considered.
The corresponding transform_result will be the null value.
This field is a member of oneof transform_type
.
Type
google.cloud.firestore_v1.types.ArrayValue
remove_all_from_array()
Remove all of the given elements from the array in the field. If the field is not an array, or if the field does not yet exist, it is set to the empty array.
Equivalent numbers of the different types (e.g. 3L and 3.0) are considered equal when deciding whether an element should be removed. NaN is equal to NaN, and Null is equal to Null. This will remove all equivalent values if there are duplicates.
The corresponding transform_result will be the null value.
This field is a member of oneof transform_type
.
Type
google.cloud.firestore_v1.types.ArrayValue

target_id()
The target ID to which this filter applies.
Type
count()
The total count of documents that match [target_id][google.firestore.v1.ExistenceFilter.target_id].
If different from the count of documents in the client that match, the client must manually determine which documents no longer match the target.
The client can use the unchanged_names
bloom filter to
assist with this determination by testing ALL the document
names against the filter; if the document name is NOT in the
filter, it means the document no longer matches the target.
Type
unchanged_names()
A bloom filter that, despite its name, contains the UTF-8
byte encodings of the resource names of ALL the documents
that match
[target_id][google.firestore.v1.ExistenceFilter.target_id],
in the form
projects/{project_id}/databases/{database_id}/documents/{document_path}
.
This bloom filter may be omitted at the server’s discretion, such as if it is deemed that the client will not make use of it or if it is too computationally expensive to calculate or transmit. Clients must gracefully handle this field being absent by falling back to the logic used before this field existed; that is, re-add the target without a resume token to figure out which documents in the client’s cache are out of sync.

partition_count()
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.
Type
page_token()
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

partitions()
Partition results. Each partition is a split point that can be used by RunQuery as a starting or end point for the query results. The RunQuery requests must be made with the same query supplied to this PartitionQuery request. The partition cursors will be ordered according to same ordering as the results of the query supplied to PartitionQuery.
For example, if a PartitionQuery request returns partition cursors A and B, running the following three queries will return the entire result set of the original query:
query, end_at A
query, start_at A, end_at B
query, start_at B
An empty result may indicate that the query has too few results to be partitioned.
Type
MutableSequence[google.cloud.firestore_v1.types.Cursor]

COUNT_UP_TO(1) AS count_up_to_1,
COUNT_UP_TO(2),
COUNT_UP_TO(3) AS count_up_to_3,
COUNT(*)
OVER (
...

becomes:
AGGREGATE
COUNT_UP_TO(1) AS count_up_to_1,

Type
class Avg(mapping=None, *, ignore_unknown_fields=False, **kwargs)
Bases: proto.message.Message

Only numeric values will be aggregated. All non-numeric values including
NULL
are skipped.If the aggregated values contain
NaN
, returnsNaN
. Infinity math follows IEEE-754 standards.If the aggregated value set is empty, returns
NULL
.Always returns the result as a double.
field()
The field to aggregate on.
Type
google.cloud.firestore_v1.types.StructuredQuery.FieldReference
class Count(mapping=None, *, ignore_unknown_fields=False, **kwargs)
Bases: proto.message.Message
Count of documents that match the query.
The COUNT(\*)
aggregation function operates on the entire
document so it does not require a field reference.
up_to()
Optional. Optional constraint on the maximum number of documents to count.
This provides a way to set an upper bound on the number of documents to scan, limiting latency, and cost.
Unspecified is interpreted as no bound.
High-Level Example:
AGGREGATE COUNT_UP_TO(1000) OVER ( SELECT * FROM k );
Requires:
Must be greater than zero when present.
Type
class Sum(mapping=None, *, ignore_unknown_fields=False, **kwargs)
Bases: proto.message.Message
Sum of the values of the requested field.
Only numeric values will be aggregated. All non-numeric values including
NULL
are skipped.If the aggregated values contain
NaN
, returnsNaN
. Infinity math follows IEEE-754 standards.If the aggregated value set is empty, returns 0.
Returns a 64-bit integer if all aggregated numbers are integers and the sum result does not overflow. Otherwise, the result is returned as a double. Note that even if all the aggregated values are integers, the result is returned as a double if it cannot fit within a 64-bit signed integer. When this occurs, the returned value will lose precision.
When underflow occurs, floating-point aggregation is non-deterministic. This means that running the same query repeatedly without any changes to the underlying values could produce slightly different results each time. In those cases, values should be stored as integers over floating-point numbers.
field()
The field to aggregate on.
Type
google.cloud.firestore_v1.types.StructuredQuery.FieldReference
class google.cloud.firestore_v1.types.StructuredQuery(mapping=None, *, ignore_unknown_fields=False, **kwargs)

The collections to query.
Type
MutableSequence[google.cloud.firestore_v1.types.StructuredQuery.CollectionSelector]
where()
The filter to apply.
Type
google.cloud.firestore_v1.types.StructuredQuery.Filter
order_by()
The order to apply to the query results.
Firestore allows callers to provide a full ordering, a partial ordering, or no ordering at all. In all cases, Firestore guarantees a stable ordering through the following rules:
The
order_by
is required to reference all fields used with an inequality filter.All fields that are required to be in the
order_by
but are not already present are appended in lexicographical ordering of the field name.If an order on
__name__
is not specified, it is appended by default.
Fields are appended with the same sort direction as the last order specified, or ‘ASCENDING’ if no order was specified. For example:
ORDER BY a
becomesORDER BY a ASC, __name__ ASC
ORDER BY a DESC
becomesORDER BY a DESC, __name__ DESC
WHERE a > 1
becomesWHERE a > 1 ORDER BY a ASC, __name__ ASC
WHERE __name__ > ... AND a > 1
becomesWHERE __name__ > ... AND a > 1 ORDER BY a ASC, __name__ ASC
Type
MutableSequence[google.cloud.firestore_v1.types.StructuredQuery.Order]
start_at()
A potential prefix of a position in the result set to start the query at.
The ordering of the result set is based on the ORDER BY
clause of the original query.
SELECT * FROM k WHERE a = 1 AND b > 2 ORDER BY b ASC, __name__ ASC;
This query’s results are ordered by
(b ASC, __name__ ASC)
.
Cursors can reference either the full ordering or a prefix
of the location, though it cannot reference more fields than
what are in the provided ORDER BY
.
Continuing off the example above, attaching the following start cursors will have varying impact:
START BEFORE (2, /k/123)
: start the query right beforea = 1 AND b > 2 AND __name__ > /k/123
.START AFTER (10)
: start the query right aftera = 1 AND b > 10
.
Unlike OFFSET
which requires scanning over the first N
results to skip, a start cursor allows the query to begin at
a logical position. This position is not required to match
an actual result, it will scan forward from this position to
find the next document.
Requires:
The number of values cannot be greater than the number of fields specified in the
ORDER BY
clause.Type
google.cloud.firestore_v1.types.Cursor
end_at()
A potential prefix of a position in the result set to end the query at.
This is similar to START_AT
but with it controlling the
end position rather than the start position.
Requires:
The number of values cannot be greater than the number of fields specified in the
ORDER BY
clause.Type
google.cloud.firestore_v1.types.Cursor
offset()
The number of documents to skip before returning the first result.
This applies after the constraints specified by the
WHERE
, START AT
, & END AT
but before the
LIMIT
clause.
Requires:
The value must be greater than or equal to zero if specified.
Type
limit()
The maximum number of results to return.
Applies after all other constraints.
Requires:
The value must be greater than or equal to zero if specified.

Type
read_time()
The consistent read_time
for the given target_ids
(omitted when the target_ids are not at a consistent
snapshot).
The stream is guaranteed to send a read_time
with
target_ids
empty whenever the entire stream reaches a
new consistent snapshot. ADD, CURRENT, and RESET messages
are guaranteed to (eventually) result in a new consistent
snapshot (while NO_CHANGE and REMOVE messages are not).
For a given stream, read_time
is guaranteed to be
monotonically increasing.
class TargetChangeType(value)
Bases: proto.enums.Enum
The type of change.
Values:
NO_CHANGE (0):
No change has occurred. Used only to send an updated
`resume_token`.
ADD (1):
The targets have been added.
REMOVE (2):
The targets have been removed.
CURRENT (3):
The targets reflect all changes committed before the targets
were added to the stream.
This will be sent after or with a `read_time` that is
greater than or equal to the time at which the targets were
added.
Listeners can wait for this change if read-after-write
semantics are desired.
RESET (4):
The targets have been reset, and a new initial state for the
targets will be returned in subsequent changes.
After the initial state is complete, `CURRENT` will be
returned even if the target was previously indicated to be
`CURRENT`.
