Hi There, I use the S3 output plugin for persisting the raw data of our Mulesoft applicaiton.

I have following configuration is my s3 output plugin;

```
output
{	
	s3
	{
		id => "experience_rt4_s3_backup"
		codec => line { format => "%{message}"}
		bucket => "mulesoftlogsuat"
		access_key_id => "AKIAUMTDG2VB7RD3GDNM"
		secret_access_key => "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"
		region => "ap-south-1"
		upload_workers_count => 1
		time_file => 60
		size_file => 104857600
		prefix => "experience-rt4/%{+YYYY}/%{+MMM}/%{+dd}"
	}
}

```

The default names in the s3 bucket is as follows;

Is there a way to get the names of the files shorter? Maybe some customization?

My questions points to a similar requirement as below;

> Hi, I am trying to output my logstash event to AWS S3. I want to have my own file naming convention instead of the random one generated by logstash with the patter "ls.s3.xxxx". I explored and I dont see any such options available. Can you guys let me know if this is something doabla and a way for it? Thanks

Any help greatly appreciated.
