Hi,

I'm writing a custom filter that reads from a file and generates potentially huge amount of events (based on how many lines it contains), where each line is translated to a yielded event.  
With default settings, it works well for a rather small files, but chokes for 100m+.  
How do I increase the resources to allow it to handle large amounts of data processed in the filter?  
LS\_HEAP\_SIZE doesn't seem to be related.

Using logstash 5.3.1.

Thanks!
