[PR] Improve SessionPoolExample by replacing unbounded fixed thread pool w… [iotdb]

anusha975 opened a new pull request, #17269:
URL: https://github.com/apache/iotdb/pull/17269

   This PR improves the SessionPoolExample by replacing the use of Executors.newFixedThreadPool() with a ThreadPoolExecutor backed by a bounded queue.
   
   Motivation:
   Executors.newFixedThreadPool internally uses an unbounded LinkedBlockingQueue, which may allow unlimited task accumulation and potentially lead to OutOfMemoryError in high-throughput scenarios.
   
   Since this is an official example, using a bounded queue demonstrates safer best practices for users.
   
   Changes:
   
   * Replace Executors.newFixedThreadPool with ThreadPoolExecutor
   * Use ArrayBlockingQueue with bounded capacity
   * Add explanatory comment
   
   This change only affects example code and does not modify core IoTDB functionality.
