   > every hour in the metadata folder only a single file is created

   @elkhand ,  the manifests file is actually not the iceberg's metadata ,  it's a manifest file that was designed for flink (Pls see [here](https://github.com/apache/iceberg/blob/master/flink/src/main/java/org/apache/iceberg/flink/sink/ManifestOutputFileFactory.java#L53)).  The reason that we have designed the flink specific manifests is https://github.com/apache/iceberg/pull/1185/files#r478772412 . When committing the iceberg transaction during completing checkpoint,  the iceberg-files-committer will read all data files from this flink specific manifest file to construct a new __iceberg__ manifest files.   You could see more details in this issue https://github.com/apache/iceberg/issues/1959. 
   
   For your issue,  I'm pretty sure that flink did not commit any iceberg transaction after you enabled the version feature in S3 bucket.  But I'm not sure what's the reason causing this.  Did you have any logs indicating the flink job was failover  (error log or stacktrace ? ) .
