I'm using spark structured streaming to process data from a streaming data source, and I'm using a file sink. Data will be put into hdfs after processing.

I've got a problem that output file is something like `part-00012-8d701427-8289-41d7-9b4d-04c5d882664d-c000.txt`. This makes me impossible get files output during last hour.

Is is possible to customize the output file into timestamp\_xxx or something like this? Or, can I output into different path by each batch?
