BloomFilter
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.

for the field path syntax reference.
transform_type
. The transformation to apply on the field. transform_type
can be only one of the following:set_to_server_value
Sets the field to the given server value.
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.
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.
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.
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.
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.
ServerValue
A value that is calculated by the server.
Enums | |
---|---|
SERVER_VALUE_UNSPECIFIED
|
Unspecified. This value must not be used. |
REQUEST_TIME
|
The time at which the server processed the request, with millisecond precision. If used on multiple fields (same or different documents) in a transaction, all the fields will get the same server timestamp. |
ExecutionStats
Execution statistics for the query.
Fields | |
---|---|
results_returned
|
Total number of results returned, including documents, projections, aggregation results, keys. |
execution_duration
|
Total time to execute the query in the backend. |
read_operations
|

It could include: { "indexes_entries_scanned": "1000", "documents_scanned": "20", "billing_details" : { "documents_billable": "20", "index_entries_billable": "1000", "min_query_cost": "0" } } |
ExistenceFilter
A digest of all the documents that match a given target.
Fields | |
---|---|
target_id
|
The target ID to which this filter applies. |
count
|
The total count of documents that match 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
|
A bloom filter that, despite its name, contains the UTF-8 byte encodings of the resource names of ALL the documents that match 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. |
ExplainMetrics
Explain metrics for the query.
Fields | |
---|---|
plan_summary
|
Planning phase information for the query. |
execution_stats
|
Aggregated stats from the execution of the query. Only present when |

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

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, or that the query is not yet supported for partitioning.

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,
COUNT_UP_TO(2) AS field_1,
COUNT_UP_TO(3) AS count_up_to_3,
COUNT(*) AS field_2
OVER (
...
);
Requires:
- Must be unique across all aggregation aliases.
- Conform to
document field name
limitations.
operator
. The type of aggregation to perform, required. operator
can be only one of the following:count
Count aggregator.
sum
Sum aggregator.
avg
Average aggregator.
Avg
Average 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
NULL
. -
Always returns the result as a double.
Fields | |
---|---|
field
|
The field to aggregate on. |
Count
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.
Sum
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.
Fields | |
---|---|
field
|
The field to aggregate on. |
StructuredQuery
A Firestore query.
The query stages are executed in the following order: 1. from 2. where 3. select 4. order_by + start_at + end_at 5. offset 6. limit 7. find_nearest
select
Optional sub-set of the fields to return.
This acts as a DocumentMask
over the documents returned from a query. When not set, assumes that the caller wants all fields returned.
from[]
The collections to query.
where
The filter to apply.
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
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.
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.
offset
int32
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.
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.
find_nearest
Optional. A potential nearest neighbors search.
Applies after all other filters and ordering.

COSINE distance compares vectors based on the angle between them, which allows you to measure similarity that isn't based on the vectors magnitude. We recommend using DOT_PRODUCT with unit normalized vectors instead of COSINE distance, which is mathematically equivalent with better performance. See Cosine Similarity to learn more about COSINE similarity and COSINE distance. The resulting COSINE distance decreases the more similar two vectors are. |

Target
A specification of a set of documents to listen to.
target_id
int32
The target ID that identifies the target on the stream. Must be a positive number and non-zero.
If target_id
is 0 (or unspecified), the server will assign an ID for this target and return that in a TargetChange::ADD
event. Once a target with target_id=0
is added, all subsequent targets must also have target_id=0
. If an AddTarget
request with target_id != 0
is sent to the server after a target with target_id=0
is added, the server will immediately send a response with a TargetChange::Remove
event.
Note that if the client sends multiple AddTarget
requests without an ID, the order of IDs returned in TargetChange.target_ids
are undefined. Therefore, clients should provide a target ID instead of relying on the server to assign one.
