MariaDB-5.5 线程池的性能测试_MySQL
MariaDB
bitsCN.comMariaDB-5.5.21-beta 是 MariaDB 首个提供全新线程池特性的版本，Oracle 在 MySQL 企业版中提供了一个商业版的线程池插件，但 MariaDB 为广大社区用户提供了一个开源的版本。
如果你还不清楚线程池，请先阅读Thread pool in MariaDB 5.5。
线程池的主要设计目的是为了提升 MariaDB 服务器在高并发下的稳定性。为了进行测试和演示，我们运行 sysbench OLTP RO 测试高达 4096 个线程用于比较新的 pool-of-threads和传统的 thread-per-connection 调度器。
下图是测试结果：
测试结果描述：
sysbench 多表 OLTP, 只读
16 个表，高达4000万行记录，10G的数据量
16G 缓冲区，避免受磁盘性能影响
mysqld 使用16 个CPU核，sysbench 使用另外8核
读/写 OLTP 压力测试结果将于近期发布

How to solve the problem of closing oracle cursor
Apr 11, 2025 pm 10:18 PM
The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.
