Review comment:
@huaxingao: As someone worked recently on the similar area. In my
experience, It is better to avoid new implementation as it needs lot of testing
(all data type * all expression) and chances of inducing issue is high.
For the unresolved expression issue with
`spark.parser.parseExpression("value") `, I recently found a way to get the
resolved expression by adding some prefix and collecting resolved expression
from plan #3757
May be can you see if it can help you as well ?
