Returns one page of the live records of a DataHub dataset, as CSV (default) or as newline-delimited JSON in the same shape as the /datahub/v1/events payload.

A time window is required: startTime is inclusive, endTime is exclusive, and the window must not exceed 366 days. Rows are ordered by their event time and event id, and pages never overlap: read the X-Next-Page-Token response header and pass it back as pageToken until the header is absent. X-Row-Count carries the number of rows in the page. Only live rows are returned; rows deleted through the console or the delete endpoints are excluded.

Every row starts with five provenance columns (event_id, batch, source, export_time, updated_by) followed by the dataset's business columns in the CSV ingest vocabulary (usage_date, fixed.<key>, label.<key>, project_label.<key>, system_label.<key>, metric.<type>). The business columns are computed from the rows of each page, so consecutive pages can have different label and metric columns; union the headers when concatenating pages. Datasets created with the FOCUS schema template use the FOCUS column names instead and can only be exported as CSV.

To re-import an export into another dataset, drop the batch, source, export_time and updated_by columns, and either drop event_id or rename it to id.
