Recently i have figured out that we can over-allocate InnoDB buffer pool size as I have already reported:

#79850

So as a result I can start MySQL with 300GB buffer pool size in my 16G laptop.

Config:

innodb_buffer_pool_size=300G
innodb_buffer_pool_instances=64

Started as:

2016-01-05 15:23:58 16211 [Note] InnoDB: Initializing buffer pool, size = 300.0G
2016-01-05 15:24:31 16211 [Note] InnoDB: Completed initialization of buffer pool

If you think that it is not harmful, let’s examine another report:

In MySQL for Visual Studio version 1.2.4 and earlier, there was an issue, existing only under a specific scenario, which was preventing the plugin to be uninstalled (either using the “Remove” option in the Windows Control Panel/Programs, or the MySQL Installer for Windows) or upgraded to a newer version, causing the uninstall/update action to be rolled back during the process. (For further information about this issue please refer to http://bugs.mysql.com/bug.php?id=71226).

Such scenario can be achieved as follows:

1. First install Visual Studio 2012, or VS 2013 or VS 2015
