This blog will discuss some recent developments with MySQL document store.

Starting MySQL 5.7.12, MySQL can be used as a real document store. This is great news!

One of our customers recently ran into a problem, where he wanted to have a preferred donor for SST, whenever a node came up. The problem was, that the node did not come up, when the preferred donor was not running.

In the documentation, you can find the parameter wsrep_sst_donor, which prefers the specified node as SST donor. This is great, as long as the donor is actually running.

The problem can be fixed by adding a comma to the end of the value of wsrep_sst_donor, what would look like this:

wsrep_sst_donor="galera2,"

Note the comma at the end of the value. This trailing comma basically tells this node, that galera2 is the preferred donor, if galera2 is not available, any other available node will be used as donor.

"Latest symlink"A "latest" symlink, is a symbolic link (on Linux, Unix etc) which links to the "latest" version of a file.
Suppose we have a file which takes some effort to create, which is generated periodically or in response to some stimulus (e.g. user activity). Then we want to create a "latest version" symlink.
Ideally the properties should be

• latest symlink always points at the latest version (duuh!)
• latest symlink always exists
• latest symlink never points at a partially completed, broken, missing or otherwise bad file

Sometimes people do this in a way which won't work.

Vsftpd is one of the most secure and fastest FTP servers for Linux. Usually vsftpd is configured to work with system users.

The classic MySQL command line tool is how most users – developers and administrators – interact with a MySQL server. From administrative tasks to trying out queries, it wouldn’t be far-fetched to call it the face of MySQL.

With a new programming interface built into the MySQL Server, we need to properly support it at the client side in connectors, tools and of course, the command line client.…
