convert_entry_type

The convert_entry_type processor converts a value type associated with the specified key in a event to the specified type. It is a casting processor that changes the types of some fields in events. Some data must be converted to a different type, such as an integer to a double, or a string to an integer, so that it will pass the events through condition-based processors or perform conditional routing.

Configuration

You can configure the convert_entry_type processor with the following options.

Usage

To get started, create the following pipeline.yaml file:

type-conv-pipeline:
  source:
    ...
  ....  
  processor:
    - convert_entry_type_type:
        key: "response_status"
        type: "integer"

copy

Next, create a log file named logs_json.log and replace the path in the file source of your pipeline.yaml file with that filepath. For more information, see Configuring Data Prepper.

For example, before you run the convert_entry_type processor, if the logs_json.log file contains the following event record:

{"message": "value", "response_status":"200"}

The convert_entry_type processor converts the output received to the following output, where the type of response_status value changes from a string to an integer:

{"message":"value","response_status":200}
