Run a query on an entry

JSON Request Body

The request body should be a JSON object with the following parameters:

{
    // Required. The type of query to run. Possible values are "QUERY" and "DELETE".
    query_type: "string"

    // Optional. The start UNIX timestamp of the query in microseconds.
    // If not set, the query starts from the beginning of the entry.
    start?: "integer"

    // Optional. The end UNIX timestamp of the query in microseconds.
    // If not set, the query continues to the end of the entry.
    end?: "integer"

    // Optional. A list of labels to include in the query.
    // Only records with all the specified labels are included.
    include?: "Dict[string, string]"

    // Optional. A list of labels to exclude in the query.
    // Records with any of the specified labels are excluded.
    exclude?: "Dict[string, string]"

    // Optional. A conditional query to filter records.
    when?: "object"

    // Optional. Return a record every S seconds
    each_s?: "float"

    // Optional. Return only every N record
    each_n?: "integer"

    // Optional. The maximum number of records to return.
    limit?: "integer"

    // Optional. If true, the query will remain open
    // for continuous data retrieval until TTL is reached.
    continuous?: "boolean"
}

Example:

{
  "query_type": "QUERY",
  "start": 1630000000000000,
  "end": 1630000001000000,
  "when": {
    "&label_name": { "$gt": 10 }
  },
  "limit": 100
}

If you use the when field in the query, read the Conditional Query Reference for more information.

Retrieve Records

If the query type is QUERY, the API returns a JSON object with the query ID:

{
  id: "integer";
}

The query ID must be used to retrieve the query results. See the Get a Record from an Entry and Get a Batch of Records from an Entry sections for more details.

Delete Records

If the query type is DELETE, the API returns a JSON object with the number of records deleted:

{
  removed_records: "integer";
}
