title: Processing and storing the excel file in database as fast as possible
body: <p>I have to process a huge Excel file and then save the data in a database. I need an advice because I am planning to use POI library for that, but my concern is: can I introduce multi-threading in it? Let's say if the Excel file is big enough can we break it in chunks and then process it? My objective is to process the file and store it in database as fast as possible.</p>
