批量插入期间MariaDB jdbc连接失败

标签: mysql jdbc mariadb

我在MariaDB中有一个使用此规范的表:

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;

我希望在此表中插入约200万条记录。 但是,在插入大约160K记录后,连接就会消失,我收到了这个例外:

但MariaDB服务器正常运行! JDBC连接器中是否有任何错误? 版本是5.5.32-MariaDB。

您是否尝试过使用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 Connector具有更大的社区优势。
