@Rocky is there way to maintain information_schema.pipe_files or will it just grow forever, is there a way to automatically removed successfully processed files after certain time?

None References • sql-reference/information_schema/pipe_files.md • loading/hdfs_load.md • knowledge/admin_and_operation/shared_data_garbage_cleanup.md • sql-reference/sql-statements/loading_unloading/pipe/SHOW_PIPES.md

drop pipe <pipe_name>

should remove it from pipe_files
