Transferred Volume(MB) size in Qlik Replicate

[Daniel_Seo]

Data size is reported differently between Transferred Volume(MB) listed in Qlik Replicate and the Target/Source table.

In Qlik Replicate the Transferred Volume(MB) is displayed as such:

         

The target or source database may show a different volume:

The data size Qlik Replicate reads (and processes) may be very different from the actual size of the data in the database. 

For example: a string column may be stored in the DB in specific encoding, using XX bytes storage. However, Qlik Replicate will request the data in multi-byte in order to avoid NLS issues, which may lead it to read twice as much data.

In addition, data Blocks, extents and segments in table may by difference before/after transferring data from source table to target table depending on Database and Journaling file system.

So the transferred volume field is not a real data of the weight of the data that was replicated at the destination? Is it more than just an estimate?
I say this because a table of  3GB was replicated from  Oracle source to Aurora Postgres, in the destination it weighs 7GB but the Qlik shows that the transferred volume was 14GB.
