MySQL 5.6: InnoDB Better Availability

dev.mysql.com/doc/refman/5.6/en/innodb-online-ddl.html

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. |

Dump and restore/warm buffer pool - Shortens warm up times after restart (from hours to minutes)

- At shutdown/startup or manually at any time

- Small footprint on disk - stores tablespace and page IDs only

MySQL 5.6: InnoDB Better Availability

dev.mysql.com/doc/refman/5.6/en/innodb-performance.html

Example:

Dump current state of Buffer Pool at shutdown:

mysql> SET innodb_buffer_pool_dump_at_shutdown=ON;

Load Buffer Pool from dump at startup:

mysql> SET innodb_buffer_pool_load_at_startup=ON;

FULLTEXT indexes on InnoDB tables

Keys on text-based content

Speeds up searches for words, phrases

Fully transactional, fast look up

Natural language/Boolean modes, proximity search, relevance ranking

MySQL 5.6: InnoDB Full Text Search create table quotes

( id int unsigned

auto_increment primary

key

,author varchar(64)

, quote varchar(4000)

, source varchar(64)

, fulltext(quote)

) engine=innodb;

select author as “Apple" from quotes

where match(quote) against (‘apple' in natural language mode);

dev.mysql.com/doc/refman/5.6/en/innodb-table-and-index.html#innodb-fulltext-index

Copyright © 2014, Oracle and/or its affiliates. All rights reserved. |

Transportable Tablespaces - Enables export/import of tables between running MySQL instances

- Faster than mysqldump (via portable .ibd files)

MySQL 5.6: InnoDB More Flexibility

CREATE TABLE t(c1 INT) engine=InnoDB;

FLUSH TABLE t FOR EXPORT; -- flush table and create the meta data file

$innodb_data_home_dir/test/t.cfg

UNLOCK TABLES;

Export:

Import: CREATE TABLE t(c1 INT) engine=InnoDB; -- if it doesn't already exist

ALTER TABLE t DISCARD TABLESPACE;

-- The user must stop all updates on the tables, prior to the IMPORT

ALTER TABLE t IMPORT TABLESPACE;

Key-value access to InnoDB

- Bypasses SQL Parsing

SQL for rich queries, JOINs, FKs, etc.

Implemented via:

- Memcached plug-in to mysqld

- Memcached mapped to native InnoDB API

- Use existing Memcached clients

- Shared process for ultra-low latency

MySQL 5.6: InnoDB More Flexibility - Memcached API
