Overhead of data in memory.

Hello

I have been uploading data on VoltDB. Recently I uploaded a csvfile of 2.6 GB (9.6 mil rows and 130 columns). The space consumed by VoltDb was almost double, approximately 5.2 GB. Can anyone tell me why is there so much overhead when we upload data. More than 120 columns are integers and the values they contain are binary.

Thanks
