定位到原因了：cassandraSessionPool会为每个线程创建个session，如果线程已经绑定了session，是不会再创建新的session的。但问题就出在我是在parallelStream情况下使用session，parallelStream底层使用的是forkJoinPool线程池，这个线程池里的线程不是创建好后就一直存在的，线程会过几分钟回收掉，等提交新任务后，会重新创建线程。这样就会导致session随着forkJoinPool里线程新建而新建，但线程死掉后又不会被回收，因为cassandraSessionPool的属性Map<Long, BackendSession> sessions会记录每次创建的session，session也没机会被close掉。 -- This is an automated message from the Apache Git Service.
