TokuDb table status

[Nikhil Bhaware]

Hello, 

 can any one tell me what is data length field in table status of tokudb..In innodb it is usually 0.but in case of tokudb it is having some large number.

when i see table status it is showing me 40gb (data length + index length) but in disk i couldn't find any file/folder occupying 40gb space.why is that?

Most likely you have a compressed table and toku shows the actual data
length rather than the physical on-disk (which depending on the data and
compression level can differ a lot).
