Logstash translate filter equivalent in fluentd?

Hi,

I have recently started exploring fluentd and currently comparing this with logstash. I would like to know how to do the equivalent of logstash’s translate filter.

For instance, how would this be done in fluentd:

logstash.conf

filter {
  # Enrich the event using the lookup_id
  translate {
    field => "lookup_id"
    destination => "enrichment_data"
    dictionary_path => "/path/to/lookup.json"
  }
}

Is there a built-in filter available for this in fluentd? If yes, can you provide an example?

I am not quite there yet with fluentd.
Any assistance is greatly appreciated.
