> Key: FLINK-10168
> URL: https://issues.apache.org/jira/browse/FLINK-10168
> Project: Flink
> Issue Type: Improvement
> Components: API / DataStream
> Affects Versions: 1.6.0
> Reporter: Bowen Li
> Priority: Not a Priority
> Labels: auto-deprioritized-major, auto-deprioritized-minor,
> auto-unassigned, pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Update: The motivation is 1) enabling users to set a read start position for
> files, so they can process files that are modified after a given timestamp 2)
> expose more file information to users and providing them with a more flexible
> file filter interface to define their own filtering rules
> ---------------
> support filtering files by modified/created time in
> {{StreamExecutionEnvironment.readFile()}}
> for example, in a source dir with lots of file, we only want to read files
> that is created or modified after a specific time.
> This API can expose a generic filter function of files, and let users define
> filtering rules. Currently Flink only supports filtering files by path. What
> this means is that, currently the API is
> {{FileInputFormat.setFilesFilters(PathFiter)}} that takes only one file path
> filter. A more generic API that can take more filters can look like this 1)
> {{FileInputFormat.setFilesFilters(List (PathFiter, ModifiedTileFilter, ...
> ))}}
> 2) or {{FileInputFormat.setFilesFilters(FileFiter),}} and {{FileFilter}}
> exposes all file attributes that Flink's file system can provide, like path
> and modified time
> I lean towards the 2nd option, because it gives users more flexibility to
> define complex filtering rules based on combinations of file attributes.
