> [UDF] beforeStart and beforeDestroy would be called more than once
> 文档中，说明了这两个方法只会被调用一次，但是实际结果并非如此。
> reproduction:
> {code}
> create function count_sec as "com.timecho.udf.normal.TestSessionTimeWindowAccessStrategy";
> CREATE DATABASE root.udf;
> CREATE TIMESERIES root.udf.d1.s1 WITH DATATYPE=text, ENCODING=PLAIN;
> CREATE TIMESERIES root.udf.d1.s2 WITH DATATYPE=text, ENCODING=PLAIN;
> insert into root.udf.d1 (time, s1, s2) values (1, 'udf', 'trigger'),(2, 'some' , 'old'),(3, null, 'trigger'),(9, 'udf', 'new'),(5, 'woman', 'udf'),(12, 'trigger', null),(14, 'udf', 14),(18, 'udf', 16),(21, 'trigger', 18),(24, 'udf', 20);
> select count_sec(s1, 'max_interval'=4, 'standard'='null') from root.udf.d1;
> {code}
> {code:shell}
