> Currently, filter condition in join have not been optimized very well, let's
> take a simple example
> {code:sql}
> select a.id, b.name from Ta a inner join Tb b on a.id = b.id and a.id < 5;
> {code}
> now, only a.id < 5 can push down, however, as for the sql above,
> we can infer a.id < 5 and b.id < 5 and both of them can push down.
