Thanks Priyanka, I would try with caching in my upcoming project.

Do you have any sample that can be helpful to me?

IMO, it's okay to keep the files in HDFS, at startup you can load them in 
memory which will be one time activity in application lifetime. Considering 
they are format/config files, it won't be difficult to cache it in memory of 
your current operator (no need to caching operator separately).

Hello Team,

I have a use case where I am trying to read number of input files with 
different formats(may be 100 source systems) and I have to parse each record.

To achieve this we need to have metadata(configuration files) of the input file 
structures. Can you please let me know that, having this metadata on HDFS is 
good or having the metadata in some sql/oracle database is good?

Assume that I don’t have caching operator for now, I need to get the 
configuration file for each source and I have to parse them at run time. To do 
this going to HDFS is good or going to database is good?

Regards,
Surya Vamshi
