I have a lot of empty messages on my Logstash indexers, I am using AWS SQS input and my attribute on SQS tier (i think it is enough time to process)

> ReceiveMessageWaitTimeSeconds == 10 sec.

Is it a responsibility of

> polling\_frequency = 3

parameter?

Founded in _[https://github.com/logstash-plugins/logstash-input-sqs](https://github.com/logstash-plugins/logstash-input-sqs)_  
Look for **sqs.rb**

```
  def polling_options
    { 
      :max_number_of_messages => MAX_MESSAGES_TO_FETCH,
      :attribute_names => SQS_ATTRIBUTES,
      :wait_time_seconds => @polling_frequency
    }
  end

```

**polling\_frequency** changes **wait\_time\_seconds** for AWS SQS **short / long polling** , yeah
