Review Comment:
> Is `VARBINARY` different from what in MySQL? I noticed this is the only
difference, maybe MySQL and StarRocks can share this type system to get max
precision.
I thought it would be the same as MySQL, but what’s strange is that the
StarRocks official website lists the maximum as 65,533
