Create stream from multiple files using "env.readFile(format, input1, FileProcessingMode.PROCESS_CONTINUOUSLY, 1000, FilePathFilter.createDefaultFilter())" ?

Hi All,

I have a use case where in need to create multiple source streams from
multiple files and monitor the files for any changes using the "
FileProcessingMode.PROCESS_CONTINUOUSLY"

Intention is to achieve something like this(have a monitored stream for
each of the multiple files), something like this:

DataStream<String> stream1 = env.readFile(format, input1,
FileProcessingMode.PROCESS_CONTINUOUSLY, 1000,
FilePathFilter.createDefaultFilter());

DataStream<String> stream2 = env.readFile(format, input2,
FileProcessingMode.PROCESS_CONTINUOUSLY, 1000,
FilePathFilter.createDefaultFilter());

DataStream<String> stream3= env.readFile(format, input3, FileProcessingMode.
PROCESS_CONTINUOUSLY, 1000, FilePathFilter.createDefaultFilter());

.

.

.

.

DataStream<String> streamN = env.readFile(format, inputN,
FileProcessingMode.PROCESS_CONTINUOUSLY, 1000,
FilePathFilter.createDefaultFilter());

Since, this implementation doesn't work, can someone suggest a way how this
thing can be achieved?


PS: Main intention is to '*monitor'* all the files and stream the updated
content if any change has been made to it.


Thank you!

Regards,

Anchit

Hi,
how does "doesn't work" manifest?

Cheers,
