Modify plugin

It modifies the content for a field. It works only with strings. You can provide an unlimited number of config parameters. Each parameter handled as cfg.FieldSelector:cfg.Substitution.

Example:

pipelines:
  example_pipeline:
    ...
    actions:
    - type: modify
      my_object.field.subfield: value is ${another_object.value}.
    ...

The resulting event could look like:

{
  "my_object": {
    "field": {
      "subfield":"value is 666."
    }
  },
  "another_object": {
    "value": 666
  }
