Collect

The "collect" transform collects (buffers) the data items from the data flow into an internal array and optionally sorts them.

Parameters

groupby

Arranges the data into consecutive batches based on the groups. This is mainly intended for internal use so that faceted data can be handled as batches.

sort

The sort order.

Example

{
  "type": "collect",
  "sort": {
    "field": ["score"],
    "order": ["descending"]
  }
}
