Apache Spark - Filtering Unprocessed File Data

Explorer

Hi,

I have a file which keeps getting appended with new lines. Its kind of log file with data in it. I need to read the data from the file store it in database.

My question is, how will i read only unprocessed records from the file and do not read already processed records using Apache Spark framework.

Thanks
