PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h linfytest3 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
Please report any problems at

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the
--defaults-file argument to mysqld_safe when starting the server
Percona Server is distributed with several useful UDF (User Defined Function) from Percona Toolkit.
Run the following commands to create these functions:
mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"
mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"

11、
一些注意事項
1、alter table xxx engine=tokudb 的情況會加metadata鎖阻塞插入更新， 而myql-5.6.17 innodb引擎則不會導致阻塞。
2、只有char, varchar, varbinary, and integer 欄位型別的擴充套件才支援online ddl【縮減不支援online 操作】，注意修改的時候欄位屬性不能發生變化，同時也不能是任何主鍵或二級索引的欄位【二級索引的話，可以先刪除二級索引，不過tokuDB建立索引二級索引並不快】，否則會導致copy表。
3、 修改列名的時候必須是單個列修改，如果是一條語句同時修改多條語句則會copy表。
4、這些欄位TIME, ENUM, BLOB, TINYBLOB, MEDIUMBLOB, LONGBLOB型別不支援online ddl。
其他的一些限制詳情可參考官網
12、tokuDB事務、鎖資訊檢視
檢視事務情況：
SELECT * FROM information_schema.tokudb_trx,
information_schema.processlist
WHERE trx_mysql_thread_id = id;
檢視鎖的情況
SELECT id FROM information_schema.tokudb_locks,
information_schema.processlist
WHERE locks_mysql_thread_id = id;
警告：
不要移動任何TokuDB相關的檔案、否則會導致資料庫崩潰並且需要使用備份才能進行恢復。
(6)、 關於TokuDB行格式
tokudb_row_format 可以設定如下的幾個值：
tokudb_default: 設定預設的壓縮行為。在 TokuDB 7.1.0版本，預設使用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。
可以使用如下命令修改行格式：
ALTER TABLE table_name ROW_FORMAT=row_format;
注意修改行格式的操作也是online 操作。
吐槽：
該引擎現在一般用於大量歷史資料的歸檔儲存，但是最致命的還是沒有一款合適的備份工具，只能使用mysqldump 備份或者停機物理備份，貌似官方的物理備份工具要收費。
TokuDB的特點：
1、高壓縮比，官方宣稱可以達到1：12。
2、高insert效能，官方稱至少比innodb高9倍。
3、可以線上新增索引和欄位，速度快。
TokuDB的缺點：
1、cpu usr態消耗高
2、響應時間變長。

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:
/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h linfytest3 password 'new-password'
Alternatively you can run:
/usr/bin/mysql_secure_installation
which will also give you the option of removing the test
databases and anonymous user created by default. This is
strongly recommended for production servers.
See the manual for more instructions.
Please report any problems at

WARNING: Default config file /etc/my.cnf exists on the system
This file will be read by default by the MySQL server
If you do not want to use this, either remove it, or use the

Percona Server is distributed with several useful UDF (User Defined Function) from Percona Toolkit.
Run the following commands to create these functions:
mysql -e "CREATE FUNCTION fnv1a_64 RETURNS INTEGER SONAME 'libfnv1a_udf.so'"
mysql -e "CREATE FUNCTION fnv_64 RETURNS INTEGER SONAME 'libfnv_udf.so'"
mysql -e "CREATE FUNCTION murmur_hash RETURNS INTEGER SONAME 'libmurmur_udf.so'"

Records: 0 Duplicates: 0 Warnings: 0
mysql> alter table timeline_1009 drop column test_flag;
Query OK, 0 rows affected (0.01 sec)
Records: 0 Duplicates: 0 Warnings: 0
11、
一些注意事項
1、alter table xxx engine=tokudb 的情況會加metadata鎖阻塞插入更新， 而myql-5.6.17 innodb引擎則不會導致阻塞。
2、只有char, varchar, varbinary, and integer 欄位型別的擴充套件才支援online ddl【縮減不支援online 操作】，注意修改的時候欄位屬性不能發生變化，同時也不能是任何主鍵或二級索引的欄位【二級索引的話，可以先刪除二級索引，不過tokuDB建立索引二級索引並不快】，否則會導致copy表。
3、 修改列名的時候必須是單個列修改，如果是一條語句同時修改多條語句則會copy表。
4、這些欄位TIME, ENUM, BLOB, TINYBLOB, MEDIUMBLOB, LONGBLOB型別不支援online ddl。
其他的一些限制詳情可參考官網
12、tokuDB事務、鎖資訊檢視
檢視事務情況：
SELECT * FROM information_schema.tokudb_trx,
information_schema.processlist
WHERE trx_mysql_thread_id = id;
檢視鎖的情況
SELECT id FROM information_schema.tokudb_locks,
information_schema.processlist
WHERE locks_mysql_thread_id = id;
警告：
不要移動任何TokuDB相關的檔案、否則會導致資料庫崩潰並且需要使用備份才能進行恢復。
(6)、 關於TokuDB行格式
tokudb_row_format 可以設定如下的幾個值：
tokudb_default: 設定預設的壓縮行為。在 TokuDB 7.1.0版本，預設使用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。
可以使用如下命令修改行格式：
ALTER TABLE table_name ROW_FORMAT=row_format;
注意修改行格式的操作也是online 操作。
吐槽：
該引擎現在一般用於大量歷史資料的歸檔儲存，但是最致命的還是沒有一款合適的備份工具，只能使用mysqldump 備份或者停機物理備份，貌似官方的物理備份工具要收費。
