This is my config. file for logstash file input plugin:  
file  
{  
id =\> "my\_plugin\_id"  
type =\> "log"  
path =\> "/uploads/_/_.log"  
mode =\> "read"  
start\_position =\> beginning  
sincedb\_clean\_after =\> "10 seconds"  
codec =\> multiline

i tried using sincedb\_clean\_after option it won't work for me.  
i am trying to re-parse old log which i had already parsed and i understand that logstash creates a db to maintain the file position of the logs and default expire is 14 days. i am trying to reduce is so that i can re-parse log files again but i am unable to do so. Whenever i restart logstash it takes the log irrespective of the scenario if it has been parsed earlier and sincedb\_clean\_after doesn't seem to work for me. i am using logstash 7.6.1 , please help me with the same. thanks.
