mysql - MariaDB jdbc 连接在批量插入期间失败

Question

我在 MariaDB 中有一个符合此规范的表:

CREATE TABLE `pages_txt` (
    `id` INT(10) UNSIGNED NOT NULL,
    `title` TEXT NOT NULL,
    `txt` MEDIUMTEXT NOT NULL,
    PRIMARY KEY (`id`)
)
COLLATE='utf8_general_ci'
ENGINE=MyISAM;

我想在这个表中插入大约 200 万条记录。 但是，在插入大约 160K 条记录后连接中断，我收到此异常:

但 MariaDB 服务器已启动并正常工作! JDBC 连接器中有任何错误吗？？？ 版本为5.5.32-MariaDB。

您是否尝试过只使用 MySQL Connector/J？ MySQL 和 MariaDB 是二进制兼容的，我从来没有遇到过任何问题。 MySQL 连接器的优势是拥有一个更大的社区。
