[GitHub] [shardingsphere] strongduanmu opened a new issue #15936: Shardingsphere JDBC has performance problem when using mysql 8.x driver
strongduanmu opened a new issue #15936:
URL: https://github.com/apache/shardingsphere/issues/15936
When we use MySQL Connector/J 8.0.27 for stress testing, we find that COM_STMT_RESET is frequently sent, which greatly reduces QPS.
We found that this problem is caused by the frequent creation/closing actual statements by ShardingSpherePreparedStatement, so caching actual statements can reduce performance loss.
