Collect

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

Parameters

groupby

Type: array

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

Type: CompareParams

The sort order.

Example

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