need help in understanding the seq file pattern reading

Post by zulfi123786 »

hi,

i am reading seq files using file pattern and have one doubt.
if i run the job and suppose it has completed reading the file from the seq file stage but is still processing the data, now if i place one more file whose name satisfies the pattern will it read the new file or as it has already completed the reading phase will it discard the new file.

Please help

I never thought about this scenario before.But, my guess would be it should discard the file.

Need to simulate it to get the confirmation though.

The regular expression is evaluated when the stage opens. The new file will be ignored - not discarded (it will still be there), just ignored - until next time you run the job.
