我正在努力批量导入一个由大约 1000 万行（或 7GB）组成的相当大的 InnoDB 表（对我来说这是迄今为止我使用过的最大的表）。

我做了一些研究如何提高 Inno 的导入速度，目前我的设置如下所示：

/etc/mysql/my.cnf/
[...]
innodb_buffer_pool_size = 7446915072 # ~90% of memory
innodb_read_io_threads = 64
innodb_write_io_threads = 64
innodb_io_capacity = 5000
innodb_thread_concurrency=0
innodb_doublewrite = 0
innodb_log_file_size = 1G
log-bin = ""
innodb_autoinc_lock_mode = 2
innodb_flush_method = O_DIRECT
innodb_flush_log_at_trx_commit=2
innodb_buffer_pool_instances=8


import is done via bash script, here is the mysql code:
SET GLOBAL sync_binlog = 1;
SET sql_log_bin = 0;
SET FOREIGN_KEY_CHECKS = 0;
SET UNIQUE_CHECKS = 0;
SET AUTOCOMMIT = 0;
SET SESSION tx_isolation='READ-UNCOMMITTED'; …
