MySQL, coupled with the InnoDB engine, provides full ACID compliance. With the addition of “eXtended Architecture” (XA) technology, they can all act in a distributed atomic environment.

In distributed systems, several different technologies, platforms and devices may need to act on separate sets of data atomically. These backend datasets can exist side by side in a datacenter, or across oceans. There can be multiple datasets where atomicity is a necessity. Foreign engines could completely control these datasets, with no concept of cross communication. The XA standard was specified by the Open Group to describe distributed transaction processing. This “eXtended Architecture” describes the relationship between a transaction manager and a transaction resource. You can find the specification HERE.

Transactions are:

• ATOMIC, committed as a …

In this blog post, I’ll examine when looking at raw MySQL query logs can be more useful than working with tools that only have summary data.

In my previous blog post, I wrote about analyzing MySQL Slow Query Logs with ClickHouse and ClickTail. One of the follow-up questions I got is when do you want to do that compared to just using tools like Percona Monitoring and Management or VividCortex, which provide a beautiful interface for detailed analyses (rather than spartan SQL interface).

In this blog post, we’ll look at how to turn on binlog encryption in Percona Server for MySQL.

Why do I need this?

As you probably know, Percona Server for MySQL’s binlog contains sensitive information. Replication uses the binlog to copy events between servers. They contain all the information from one server so that it can be applied on another. In other words, if somebody has access to a binlog, it means they have access to all the data in the server. Moreover, said person (or, “Hacker”) could create a clone copy of our server by just making a replica of it. In the end, they have access to our binlog. This shows how important protecting a binlog really is – leakage of binlogs not only make a particular table/tablespace or a group of tables accessible to a hacker, but literally the whole server …
