Abstract

MySQL Document Store enables us to work with SQL relational tables and schema-less JSON collections. So instead of having a mixed bag of databases, you can just rely on MySQL, where the JSON documents can be stored in collections and managed with CRUD operations. All you need to do is install the X plugin. In this session, you will learn what a document store is, how to install and use it, and all the reasons for considering it. We will also see several specific features helping developers and illustrate how the usual MySQL DBA can manage this new world.

While we have documented how you might consider Monitoring a Cluster with Galera Manager, we’d also like to take you through a bit more of what is available, before our webinar this week. Please signup for a live demo from install to deployment and management.

You might be used to SHOW GLOBAL STATUS LIKE 'wsrep_%'; from the command line, but why not take a look at all of this on a graph, over time, within the GUI of the Galera Manager? What happens when you feel a node is getting overwhelmed? You tend to check wsrep_flow_control_paused, which returns the percentage of time the node was paused because of Flow Control (normally you do this after a FLUSH STATUS however now you …

Migrating your database to a new datacenter can be a high-risk and time-consuming process. A database contains state, and can be much harder to migrate as compared to web servers, queues or cache servers.

In this blog post, we will give you some tips on how to migrate your data from one service provider to another. The process is somewhat similar to our previous post on how to upgrade MySQL, but there are a couple of important differences.

MySQL Replication or Galera Cluster?

Switching to another service provider (e.g., moving from AWS to Rackspace or from colocated servers to cloud) very often means one would build a brand new infrastructure in parallel, sync it with the old infrastructure and then switch over to it. To connect and sync them, you may want to leverage MySQL replication.

If you are using …

Yes, your read the title correctly: an unprivileged user can crash your MySQL Server.  This applies for the default configuration of MySQL 8.0.21 (and it is probably the case for all MySQL 8 GA versions).  Depending on your configuration, it might also be the case for MySQL 5.7.  This needs malicious intent and a lot of determination, so no need to panic as this will not happen by

Changing the default value (3) of log_error_verbosity in MySQL/Percona Server for MySQL 5.7 can have a hidden unintended effect! What does log_error_verbosity do exactly? As per the documentation:

“The log_error_verbosity system variable specifies the verbosity for handling events intended for the error log.“

Basically a value of 1 logs only [Errors]; 2 is 1)+[Warnings]; and 3 is 2)+[Notes].

For example, one might be tempted to change the default of log_error_verbosity since the error.log might be bloated with thousands (or millions) of lines with [Notes], such as:

2020-10-08T17:02:56.736179Z 3 [Note] Access denied for user 'root'@'localhost' (using password: NO)
2020-10-08T17:04:48.149038Z 4 [Note] Aborted connection 4 to db: 'unconnected' user: 'root' host: 'localhost' (Got timeout reading communication packets)

(P.S. you can read more about those Notes on this other Percona blog posts):
