If you can find them you could just stat the modified date and size of the raw datafiles or compare md5 hashes of the files.

Depending on how you can sort the data with sql you may just be able to take a look at the first x rows and/or the last x rows of the table instead of building a complete array.

Also depending on your data you could maybe checksum a column.
