We are using logstash distributed pattern as below

main.conf  
input {kinsis }  
output {  
if condition 1 then  
pipeline 1  
else if condition 2 then  
pipeline 2  
}

pipeline1.conf  
input {pipeline1}  
filter {}  
output {amazonES}

We are using persistent queue with queue size as more than 64MB.  
We have almost 100 pipelines in main.conf.We are running this config in docker on ec2 linux instance.  
Now our question is if our linux instance terminated, then Will we loose inflight events.
