]
Chesnay Schepler closed FLINK-27330.
------------------------------------
Resolution: Information Provided
Because the underlying source implementation
(FileMonitoringFunction/FileReadFunction) has several flaws, one of which is no
support for checkpointing / exactly-once processing (e.g., it doesn't remember
whether it has already processed a given file when the job has restarted).
> Why Read File Stream Function Deprecated?
