How much is cached

Hi all.

I'm implementing a filesystem that resides inside a MySQL database using
FUSE[1]. The actual data of my files is stored in fields of type BLOB
and what I want to know is: Does MySQL cache the contents of a BLOB in
its buffer cache? What I mean is, if I do two consequtive calls to the
database that select out the contents of a BLOB, will the BLOB be read
only once (and found in cache the other time), or will it be read from
disk twice?

Best regards,
Mads Kristensen
