Hello,  
I am currently having an issue with property **sincedb\_path**. My logstash service is dockerized and when using this plugin I do not have to implicitly set the sincedb\_path attribute because internally logstash will create the directory structure to house the sincedb files. Now for some reason the directory is created successfully but the db files are not created which means the offset is not written, so the dead letter queue file will get re-read from the beginning when the logstash service is restarted.

logstash.conf  
input {  
dead\_letter\_queue {  
path =\> "/opt/logstash/persistance/data/dead\_letter\_queue"  
commit\_offsets =\> true  
}  
}  
output {  
file {  
path =\> "/app/platform/logstash/logs/dead\_letter\_queue.log"  
codec =\> line {  
format =\> "Metadata: %{[@metadata]} | Event: %{message} | Timestamp: %{[@timestamp]}"}  
}  
}

Any ideas?...
