Thanks Shammon. Is there any way to verify that File Source reads files directly from S3?

However, Flink also supports configuring temporary directories through `io.tmp.dirs`. If it is a user-defined source, it can be obtained from FlinkS3FileSystem. After the Flink job is completed, the directory will be cleaned up.

Please help me on below questions- 1. When Split Enumerator assigns split to Source Reader, does it downloads the file temporarily and then starts reading/decoding the records from file or it creates direct stream with S3? 1. If it is downloaded locally then on which path? Is it configurable? 1. Does this temporary file automatically gets deleted or any explicit cleanup is required? Regards, Kirti Dhar
