json_array

Available in: Cloud, Self-Managed

Consumes a stream of one or more JSON elements within a top level array. This scanner is useful for:

  • Processing exports from systems that generate a JSON array as the top-level JSON structure (for example, logs, bulk exports, etc).

  • Efficiently breaking up large files with many objects into individual events/messages.

Suppose you have a file events.json:

events.json
[
  {"event": "login", "user": "alice"},
  {"event": "logout", "user": "bob"},
  {"event": "purchase", "user": "carol", "amount": 42}
]

The configuration to process this file is:

input:
  file:
    paths: [ "./events.json" ]
    scanner:
      json_array: {}

Result: Each event in the array is processed as a separate message.

Requirements

The json_array scanner expects the input to be a single JSON array, where each array element is a JSON object or value.

Fields

The json_array scanner has no required fields. You declare it as {} in your config.

json_array: {}
