Deep Dive: Adding Replication and Scaling with Galera

Wednesday, April 12 1:10 pm – 2:00 pm.

Seppo  Jaakola, Codership CEO

Data inconsistency is the worst problem that can happen for a synchronous database cluster. At some point it will appear during replication processing, simply because the application of replication events is not possible in some cluster nodes due to missing rows, excessive rows or wrong values in the row columns. As a result, this usually stops the replication process ...READ MORE

Innotop: A real-time, advanced investigation tool for MySQL

GUI monitoring tools for MySQL are not always suitable for all our needs or situations. Most of them are designed to provide historical views into what happens to our database over time rather then real-time insight into current MySQL server status. Excellent free tools for this include Cacti, Zabbix, Ganglia, Nagios, etc. But each of them needs to be properly configured to provide details on what is going on in our MySQL instances. And setting up one of these monitoring solutions is neither quick nor trivial (well, maybe with the exception of Ganglia).

MySQL Workbench provides …

Is Synchronous Replication right for your app?

I talk with lot of people who are really interested in Percona XtraDB Cluster (PXC) and mostly they are interested in PXC as a high-availability solution.  But, what they tend not to think too much about is if moving from async to synchronous replication is right for their application or not.

Facts about Galera replication

There’s a lot of different facts about Galera that come into play here, and it isn’t always obvious how they will affect your database workload.  For example:

  • Transaction commit takes approximately the worst packet round trip time (RTT) between any two nodes in your cluster.
  • Transaction apply on slave nodes is still asynchronous from client commit (except on the original node where the transaction is committed)
  • Galera prevents writing conflicts to these pending transactions …
