Hi,  
We use beats to send most of our logs to logstash with the following parameters:

- bulk\_size: 2048
- load\_balanced: yes
- workers: number of logstashes
- pipelining: 2

In logstash we have 8 worker threads with 2 cores and 4GB HEAP. The question I have is does the internal batch sizing in logstash need to correlate with the bulk\_size a beat might be sending? That is, does it need to be larger?

Regards,  
David
