Request body

The request body contains data with the following structure:

JSON representation 
{
  "explainOptions": {
    object (ExplainOptions)
  },

  // Union field query_type can be only one of the following:
  "structuredQuery": {
    object (StructuredQuery)
  }
  // End of list of possible types for union field query_type.

  // Union field consistency_selector can be only one of the following:
  "transaction": string,
  "newTransaction": {
    object (TransactionOptions)
  },
  "readTime": string
  // End of list of possible types for union field consistency_selector.
}
Fields
explainOptions

object (ExplainOptions)

Optional. Explain options for the query. If set, additional query statistics will be returned. If not, only query results will be returned.
Union field query_type. The query to run. query_type can be only one of the following:
structuredQuery

object (StructuredQuery)

A structured query.
Union field consistency_selector. The consistency mode for this transaction. If not set, defaults to strong consistency. consistency_selector can be only one of the following:
transaction

string (bytes format)

Run the query within an already active transaction.

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

A base64-encoded string.
newTransaction

object (TransactionOptions)

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.
readTime

string (Timestamp format)

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.

Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".

Response body

The response for Firestore.RunQuery.

If successful, the response body contains data with the following structure:

JSON representation 
{
  "transaction": string,
  "document": {
    object (Document)
  },
  "readTime": string,
  "skippedResults": integer,
  "explainMetrics": {
    object (ExplainMetrics)
  },

  // Union field continuation_selector can be only one of the following:
  "done": boolean
  // End of list of possible types for union field continuation_selector.
}
Fields
transaction

string (bytes format)

The transaction that was started as part of this request. Can only be set in the first response, and only if RunQueryRequest.new_transaction was set in the request. If set, no other fields will be set in this response.

A base64-encoded string.
document

object (Document)

A query result, not set when reporting partial progress.
readTime

string (Timestamp format)

The time at which the document was read. This may be monotonically increasing; in this case, the previous documents in the result stream are guaranteed not to have changed between their readTime and this one.

If the query returns no results, a response with readTime and no document will be sent, and this represents the time at which the query was run.

Uses RFC 3339, where generated output will always be Z-normalized and uses 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
skippedResults

integer

The number of results that have been skipped due to an offset between the last response and the current response.
explainMetrics

object (ExplainMetrics)

Query explain metrics. This is only present when the RunQueryRequest.explain_options is provided, and it is sent only once with the last response in the stream.
Union field continuation_selector. The continuation mode for the query. If present, it indicates the current query response stream has finished. This can be set with or without a document present, but when set, no more results are returned. continuation_selector can be only one of the following:
done

boolean

If present, Firestore has completely finished the request and no more documents will be returned.
