我正忙于构建现有数据库的从属。我不希望它在将从属设备与主设备处于相同状态之前为我导入的数据构建 bin 日志。

这主要是为了节省导入 100 G 数据的空间。

mysqldump somelargedb | gzip > /somewhere/withspace/dump/somelargedb.sql.gz

未压缩的此文件在 100 Gb 范围内。压缩后大约为 2Gb

我最近打破了复制，当我试图通过一个不正确的交易时。我得到了以下内容。

MariaDB [(none)]> STOP SLAVE;
Query OK, 0 rows affected (0.05 sec)

MariaDB [(none)]> SET GLOBAL SQL_SLAVE_SKIP_COUNTER = 1;
ERROR 1966 (HY000): When using parallel replication and GTID with multiple replication domains, @@sql_slave_skip_counter cannot be used. Instead, setting @@gtid_slave_pos explicitly can be used to skip to after a given GTID position.

MySQL 无法在 Arch Linux 上启动。

我有下表。

我也想加分区。

CREATE TABLE `app_log_Test` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `dateCreated` datetime NOT NULL,
  `host` varchar(512) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `label` varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `event` varchar(32) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `level` varchar(8) COLLATE utf8mb4_unicode_ci DEFAULT NULL,
  `message` text COLLATE utf8mb4_unicode_ci,
  `version` bigint(20) NOT NULL DEFAULT '0',
  PRIMARY KEY (`id`),
  KEY `app_log_dateCreated` (`dateCreated`),
  KEY `app_log_label` (`label`),
  KEY `app_log_event` (`event`),
  KEY `app_log_level` (`level`)
) ENGINE=TokuDB `COMPRESSION`=tokudb_quicklz

我正在使用 MariaDB 10。
