>
> Iceberg provides a rich API to push down predicates, e.g. we could push down
> complex predicates with OR, NOT, etc.
> Also, currently we only push down predicates in the form:
> {noformat}
> COL <bin-operator> LITERAL_EXPR
> E.g.:
> col_ts <= '2021-01-01 12:01:00'
> {noformat}
> Instead of only allowing literal expressions, we could evaluate any constant
> expression and push down the result to Iceberg.
