> Spark can't push down filter condition of Or:
> Such as if I have a table {color:#d04437}default.test{color}, his partition col is "{color:#d04437}dt{color}",
> if I use query : 
> {code:java}
> select * from default.test where dt=20190625 or (dt = 20190626 and id in (1,2,3) )
> {code}
> In this case, Spark will resolve or condition as one expression, and since this {color:#333333}expr {color}has reference of "{color:#FF0000}id{color}", then it can't been push down.
