Disclosure -- I received a copy of this book from the publisher for review.

The MariaDB Cookbook is well written by someone who knows the MariaDB database server quite well. Writing a 300 page book by yourself is no small feat and Daniel has done it with aplomb. I am most familiar with Percona server and Oracle's MySQL server but I have been interested in MariaDB for some of its new features -- especially the multi-source replication. I took a look at this section in particular and it was well done with clear step by step instructions on how to accomplish multi-source replication. Each of the recipes follow this pattern with clear, concise steps. My only complaint about the cookbook items are that they might be that they are a little too concise at times -- although to Daniel's credit there are frequent See Also sections that point to deeper details.

As I read through the cookbook I kept thinking …

A recurring and very common customer issue seen here at the Percona Support team involves how to make the ibdata1 file “shrink” within MySQL. I can only imagine there’s a degree of regret by some of the InnoDB architects on their design decisions regarding disk-space management by the shared tablespace* because this has been a big frustration for many MySQL users over the years.

There’s a very old bug (“InnoDB ibdata1 never shrinks after data is removed,” Sept. 8 2003) documenting user dissatisfaction. Shortly before that issue celebrated its 10th anniversary, James Day, MySQL senior principal support engineer at Oracle, posted a comment explaining why things haven’t changed and he also offered possible alternative solutions. Maybe we’ll …

While certainly not ready for production here is something to look forward to in MySQL 5.7:

"As of MySQL 5.7.5, the innodb_buffer_pool_size parameter is dynamic, allowing you to resize the buffer pool without restarting the server. The resizing operation, which involves moving pages to a new location in memory, is performed chunks. Chunk size is configurable using the new innodb_buffer_pool_chunk_size configuration option. You can monitor resizing progress using the new  …

Edit: added sample table output in MySQL

MySQL Workbench 6.2 introduces support for MS Access migration. This tutorial should help you get your Access tables, indexes, relationships and data in MySQL.

Preparation

Because MS Access ODBC drivers are only available for Windows, migrating from it is also only possible from Windows. As for the destination MySQL server, you can have it in the same local machine or elsewhere in your network.

MS Access stores relationship/foreign key information in an internal table called MSysRelationships. That table is protected against read access even to the Admin user, so if you try to migrate without opening up access to it, you will get an error like this:

[42000] [Microsoft][ODBC Microsoft Access Driver] Record(s) cannot be read; no read permission on 'msysobjects'. (-1907) (SQLExecDirectW)

The steps to grant read access to …
