I use logstash-input-file-plugin.  
when I rename file and restart , logstash will read duplication.

I rotate log in the way renaming method.

The scene is as follows：  
During the logstash shutdown, the **service.log** is renamed **service.log.2020-03-06** and create a new file named **service.log** , when I restart logstash, it will reread content in **service.log.2020-03-06**.  
Are there any good suggestions to avoid this situation？

config:  
input {  
file {  
path =\> ["/home/service.\*”]  
start\_position =\> "beginning"  
}  
}

logstash version: logstash-7.6.0
