> Key: BEAM-14267
> URL: https://issues.apache.org/jira/browse/BEAM-14267
> Project: Beam
> Issue Type: New Feature
> Components: io-java-files
> Reporter: Yi Hu
> Assignee: Yi Hu
> Priority: P2
> Time Spent: 3h 40m
> Remaining Estimate: 0h
>
> In TextIO and AvroIO, we have a configuration option called watchForNewFiles,
> and in FileIO.MatchConfiguration, we have an option called watchInterval.
> Right now, these match any files according to the filtering criteria, and
> then periodically check for new files. A file is determined to be new if it
> has a different filename than a file that has already been read.
> We want to add an option to choose to consider a file new if it has a
> different timestamp from an existing file, even if the file itself has the
> same name.
> See the following design doc for more detail:
