Some qustion with the class 'SessionPool'

[hesy007]

1. Why add syncronized to the method public synchronized ResultSet execute(String stmt, Map<String, Object> parameterMap)?
2. and why this method has been marked as 'deprecated' ?

[Nicole00]

the synchronized lock is unnecessary, it has been removed.
For sessionPool, our original intention is to provide a thread-safe execution entry that is convenient for users to use for multi-threads. So we plan to only provide the execute interface and not encapsulate other interfaces.
