> This issue aims to supports generating optimized plan for join on stream.
> The query will be converted to window join if join condition contains window bounds, otherwise will be converted to normal join.
> e.g.
> Queries similar to the following should be window join:
> {code:sql}
> SELECT t1.a, t2.b FROM MyTable t1 JOIN MyTable2 t2 ON
> t1.a = t2.a AND
> t1.proctime BETWEEN t2.proctime - INTERVAL '1' HOUR AND t2.proctime + INTERVAL '1' HOUR
> {code}
