removeDuplicates Takes more time


I have added a removeDuplicates method for an excel which has more than 2lkah rows and 10+ columns. But it takes more than an hour to remove the duplicates , is it normal thing or is there anything better option to achieve the same. I don’t have a sample excel file of more than 2 lkh records my bad.



We evaluated your issue a bit. We think this is an issue with Cells.removeDuplicates regarding performance. We need to investigate if/why Cells.removeDuplicates takes more time for large dataset. I have logged a ticket with an id “CELLSJAVA-43043” for your issue. We will try to enhance the performance (if appropriate).

Once we have an update on it, we will let you know.


This is to inform you that we have fixed your issue (logged earlier as “CELLSJAVA-43043”) now. We will soon provide you the fixed version after performing QA and incorporating other enhancements and fixes.
