Check if we are using MyISAM.
If this is a myisam table, then we cannot do a memcmp
right away because some NULL fields can still contain
an old value in the row - they are not shown to the user
because the null bit is set, however, the contents are
not cleared. As such, plain memory comparison cannot be
assured to work. See: BUG#49482 and BUG#49481.
On top of this, we do not store field contents for null
fields in the binlog, so this is extra important when
comparing records fetched from binlog and from storage
engine.

/**
Check if we are using MyISAM.
If this is a myisam table, then we cannot do a memcmp
right away because some NULL fields can still contain
an old value in the row - they are not shown to the user
because the null bit is set, however, the contents are
not cleared. As such, plain memory comparison cannot be
assured to work. See: BUG#49482 and BUG#49481.
On top of this, we do not store field contents for null
fields in the binlog, so this is extra important when
comparing records fetched from binlog and from storage
engine.
