線上的數據增長越來越快，數據量的增長也愈來愈大，尤其是日志類數據，這對於數據遷移、數據備份恢復而言，都是一個非常大的挑戰。
於是想到了 13 年開源 tokuDB 存儲引擎，來解決我們迫在眉睫的容量問題。
TokuDB 是一個高性能、支持事務處理的 MySQL 和 MariaDB 的存儲引擎。TokuDB 的主要特點是高壓縮比，高 INSERT 性能，支持大多數在線修改索引、添加字段，特別適合像 Zabbix 這種高 INSERT，少 UPDATE 的應用場景。
由於在 Percona 5.6 之后，tokuDB 無法單獨作為一個插件直接在 MySQL 社區版上使用（可以成功安裝插件，但使用時會陷入無限重啟/(ㄒoㄒ)/~~），因而，本次使用 Percona MySQL 最新版 5.7.18，操作系統是 64 bit CentOS 6.9。
安裝
1 依賴安裝
yum install libaio-devel numactl -y
2 初始化安裝和 MySQL 社區版安裝一樣
3 關閉 MySQL 服務，添加 tokuDB 插件配置，並啟動
[mysqld_safe]
malloc-lib=/usr/lib64/libjemalloc.so.1
plugin-dir = /usr/local/mysql/lib/mysql/plugin/
plugin-load=ha_tokudb.so
注意：5.7 以后版本，為了安全，需要將 libjemalloc 復制到 /usr/lib /usr/lib64 目錄下才能正確讀取
4 安裝 tokuDB
ps_tokudb_admin -S /tmp/mysql.sock --enable -uroot -pxxx
注意：此時可以加上 --enable-backup 熱備份插件功能
5 添加 tokuDB 配置項
##tokuDB
#tokudb-data-dir = /data/mysql/mysql3306/tokudbData
#tokudb-log-dir = /data/mysql/mysql3306/tokudbLog
#TokuDB的行模式，建議用 FAST ，如果磁盤空間很緊張，建議用 SMALL
#tokudb_default: 設置默認的壓縮行為。在 TokuDB 7.1.0版本，默認使用 zlib 庫進行壓縮，未來版本可能會改變。
#tokudb_fast: 使用 quicklz 庫的壓縮模式。
#tokudb_small: 使用 lzma 庫的壓縮模式。
#tokudb_zlib: 使用 zlib 庫的壓縮模式，提供了中等級別的壓縮比和中等級別的CPU消耗。
#tokudb_quicklz: 使用 quicklz 庫的壓縮模式， 提供了輕量級的壓縮比和較低基本的CPU消耗。
#tokudb_lzma: 使用 lzma 庫壓縮模式，提供了高壓縮比和高CPU消耗。
#tokudb_uncompressed: 不使用壓縮模式。
tokudb_row_format = tokudb_fast
tokudb_cache_size = 1G ###建議內存的一半
tokudb_commit_sync = 0
tokudb_directio = 1
tokudb_read_block_size = 128K
tokudb_read_buf_size = 128K
備份
1 使用 mysqldump 備份
使用 Percona 版本的 mysqldump 可以備份 tokuDB 的數據，並且額外提供了一個參數 lock-for-backup 來保證數據一致性。
eg:
mysqldump --single-transaction --lock-for-backup --master-data=2 -S /tmp/mysql.sock -uroot -p -A > xxx-2017-6-28.sql
mysqldump has also been extended with a new option, lock-for-backup (disabled by default). When used together with the --single-transaction option, the option makes mysqldump issue LOCK TABLES FOR BACKUP before starting the dump operation to prevent unsafe statements that would normally result in an inconsistent backup.
When used without the single-transaction option, lock-for-backup is automatically converted to lock-all-tables.
Option lock-for-backup is mutually exclusive with lock-all-tables, i.e. specifying both on the command line will lead to an error.
If the backup locks feature is not supported by the target server, but lock-for-backup is specified on the command line, mysqldump aborts with an error. [Link]
2 使用 tokudb-xtrabackup 備份
基於 Percona Xtrabackup 的兼容 tokuDB 的備份工具
yum install cmake gcc gcc-c++ libaio libaio-devel automake autoconf bison libtool ncurses-devel libgcrypt-devel libev-devel libcurl-devel vim-common -y
git clone https://github.com/BohuTANG/tokudb-xtrabackup
cd tokudb-xtrabackup
cmake .\
-DBUILD_CONFIG=xtrabackup_release\
-DWITH_BOOST=extra/boost/boost_1_59_0.tar.gz\
-DWITH_MAN_PAGES=OFF\
-DCMAKE_INSTALL_PREFIX=/usr/local/tokudb-xtrabackup
make
make install
注意： gcc 的版本最好要 >= 4.8
eg:
/usr/local/tokudb-xtrabackup/bin/innobackupex --defaults-file=/path/to/my.cnf --user=root --password=xxx --no-timestamp /path/to/backup
/usr/local/tokudb-xtrabackup/bin/innobackupex --apply-log /path/to/backup
/usr/local/tokudb-xtrabackup/bin/innobackupex --defaults-file=/path/to/my.cnf --copy-back /path/to/backup
3 使用 tokudb-backup-plugin 備份
官方提供的一個熱備份插件
ps_tokudb_admin --enable-backup -S /tmp/mysql.sock -uroot -pxxx
用此命令安裝之后，確認配置文件已添加相應的配置項：
# tokudb
innodb_use_native_aio=off
[mysqld_safe]
preload-hotbackup
thp-setting=never
eg:
mysql> set tokudb_backup_dir='/path/to/backup';
