So I have a .csv file that contains ~12,000 rows and on my local filesystem takes up about 3MB of data. I assumed that when I imported this csv into a Salesforce Object, the data would still take up around 3MB of space, however it ends up taking over 25MB of space.
I'm trying to figure out what causes the discrepancy between storage sizes (I assume that there are some metadata files that get created and are counted agains the org limits, however an extra 22MB of data seems unnecessary). Does anyone know what causes this and/or how I could accurately predict how much Salesforce storage a CSV file would consume before importing it into an SObject?
The CSV File in my File System:
The Size of the Data once imported into an SObject:
