Ramesh Mani commented on RANGER-4404:
-------------------------------------
[~bpatel] Thanks for raising this.
On the time taken to convert 50 gb of log , where do you think that more of the
time spent? Could parallelizing the batch process of files help in this case? I
mean multiple threads ( partitioning) based on the number of files and
processing it parallel will help in this case?
