是-每次请求都将会话数据加载到脚本的内存中.因此，您有打破单个脚本存储限制的风险.即使您没有达到极限，这实际上也没有效率.

Yes - session data is loaded into the script's memory on every request. Hence, you are at risk of breaking the individual per-script memory limit. Even if you don't hit the limit, this is really inefficient.

按需访问数据库的数据要好得多..

Accessing data from the database on demand is much better.
