> Support purging aged file entry for FileStreamSource metadata log
> -----------------------------------------------------------------
>
>                 Key: SPARK-17604
>                 URL: https://issues.apache.org/jira/browse/SPARK-17604
>             Project: Spark
>          Issue Type: Sub-task
>          Components: SQL, Streaming
>            Reporter: Saisai Shao
>            Priority: Minor

> Currently with SPARK-15698, FileStreamSource metadata log will be compacted 
> periodically (10 batches by default), this means compacted batch file will 
> contain whole file entries been processed. With the time passed, the 
> compacted batch file will be accumulated to a relative large file. 
> With SPARK-17165, now {{FileStreamSource}} doesn't track the aged file entry, 
> but in the log we still keep the full records,  this is not necessary and 
> quite time-consuming during recovery. So here propose to also add file entry 
> purging ability to {{FileStreamSource}} metadata log.
> This is pending on SPARK-15698.
