Download query result

GET 
/query/:queryId/result/download

Download the results of a completed query as single CSV file.

This endpoint returns a presigned URL that allows time-limited access to the CSV results which users should follow to download the file.

Results for a query (identified by :queryId) can only be accessed by the user who originally submitted it.

Required scope(s): [data.chf:query, data.indices:query]

The column headers of generated CSV files will adhere to the following specification:

• Query results: All headers that represent columns from the query results will have the data__ prefix, followed by the column name. For example, data__indexValue, data__timestamp etc.

• Additional metadata:

  • query_statement_name: The ID of the source query submitted via the query API.
  • record_no: A unique ID for each record.

An example of a generated CSV file would is as follows:

data__timestamp, data__deviceId, data__jobId, data__indexName, data__indexValue, query_statement_name, record_no
