Hi,  
I’m wondering if I can set the file name for something different than:`<prefix>/<topic>/year=YYYY/month=MM/day=dd/<topic>+<kafkaPartition>+<startOffset>.<format>`  
Actually I want to create a file name and in case it is already exists override the old one.  
Thanks,  
Amir

@amir I’m not sure that your specific use case is covered, but I wanted to point you to the S3 documentation around mapping records to S3 objects here.

[https://docs.confluent.io/kafka-connect-s3-sink/current/index.html#mapping-records-to-s3-objects](https://docs.confluent.io/kafka-connect-s3-sink/current/index.html#mapping-records-to-s3-objects)

Thanks Rick 👍  
Looks like it is not covered…
