Split record

The split record processing rule splits an array of JSON objects into a series of standalone records.

For a processing rule with the opposite effect, see join records.

Configuration parameters

ParameterDescriptionDefault
KeyRequired. The key that contains the array to split.none
Ignore if missing checkboxIf selected, preserve instances of Key that contain non-array data. If not selected, remove instances of Key that contain non-array data.Not selected
Ignore if array is empty checkboxIf selected, preserve instances of Key that contain an empty array. If not selected, remove instances of Key that contain an empty array.Not selected
Keep original array checkboxIf selected, include the full body of the original array inside each split object. If no Destination key is set or if Destination key is the same as Key, the original array isn't preserved.Not selected
Destination keyThe key to store the resulting split object. If unspecified, each split object is stored in a key with the same name as Key.none
CommentA custom note or description of the rule's function. This text is displayed next to the rule's name in the Actions list in the processing rules interface.none

Example

Using the split record processing rule lets you restructure your telemetry data by turning a combined array of events into multiple standalone events. For example, given these sample logs:

{"events":[
  {"timestamp":"2023-03-28T09:08:41.64283645Z","user_id":3,"page_id":30,"action":"purchase"},
  {"timestamp":"2023-03-28T09:08:42.643343109Z","user_id":4,"page_id":10,"action":"purchase"},
  {"timestamp":"2023-03-28T09:08:48.643600498Z","user_id":1,"page_id":50,"action":"click"},
  {"timestamp":"2023-03-28T09:08:50.643773688Z","user_id":5,"page_id":40,"action":"purchase"},
  {"timestamp":"2023-03-28T09:08:51.643932272Z","user_id":1,"page_id":30,"action":"purchase"},
  {"timestamp":"2023-03-28T09:08:56.644080944Z","user_id":2,"page_id":40,"action":"click"},
  {"timestamp":"2023-03-28T09:09:03.64425954Z","user_id":3,"page_id":30,"action":"click"},
  {"timestamp":"2023-03-28T09:09:03.644317046Z","user_id":1,"page_id":20,"action":"view"},
  {"timestamp":"2023-03-28T09:09:10.64447719Z","user_id":2,"page_id":50,"action":"purchase"},
  {"timestamp":"2023-03-28T09:09:17.644810963Z","user_id":2,"page_id":10,"action":"view"},
  {"timestamp":"2023-03-28T09:09:20.644994805Z","user_id":1,"page_id":50,"action":"view"}
]}

A processing rule with the Key value events and the Destination key value log returns the following result:

{"log":{"action":"purchase","user_id":3,"timestamp":"2023-03-28T09:08:41.64283645Z","page_id":30}}
{"log":{"action":"purchase","user_id":4,"timestamp":"2023-03-28T09:08:42.643343109Z","page_id":10}}
{"log":{"action":"click","user_id":1,"timestamp":"2023-03-28T09:08:48.643600498Z","page_id":50}}
{"log":{"action":"purchase","user_id":5,"timestamp":"2023-03-28T09:08:50.643773688Z","page_id":40}}
{"log":{"action":"purchase","user_id":1,"timestamp":"2023-03-28T09:08:51.643932272Z","page_id":30}}
{"log":{"action":"click","user_id":2,"timestamp":"2023-03-28T09:08:56.644080944Z","page_id":40}}
{"log":{"action":"click","user_id":3,"timestamp":"2023-03-28T09:09:03.64425954Z","page_id":30}}
{"log":{"action":"view","user_id":1,"timestamp":"2023-03-28T09:09:03.644317046Z","page_id":20}}
{"log":{"action":"purchase","user_id":2,"timestamp":"2023-03-28T09:09:10.64447719Z","page_id":50}}
{"log":{"action":"view","user_id":2,"timestamp":"2023-03-28T09:09:17.644810963Z","page_id":10}}
{"log":{"action":"view","user_id":1,"timestamp":"2023-03-28T09:09:20.644994805Z","page_id":50}}

This rule assigned each object in the original events array to a series of keys named log.
