5 great new features from Percona Cloud Tools for MySQL

It’s been three months since we announced anything for Percona Cloud Tools, not because we’ve been idle but because we’ve been so busy the time flew by!  Here’s the TL;DR to pique your interest:

  • EXPLAIN queries in real-time through the web app
  • Query Analytics for Performance Schema
  • Dashboards: customizable, shared groups of charts
  • Install and upgrade the agent with 1 command line
  • Unified UI: same time range, same host wherever you go

Percona Cloud Tools for MySQL is a hosted service providing access to query performance insights for all MySQL uses. After a brief setup, unlock new information about your database and how to improve your applications. There’s a lot more, but let’s just look at these five new features…

Introducing Percona Cloud Tools for MySQL

I am proud to announce Percona Cloud Tools, the next generation of tools for MySQL.  I have been developing tools for MySQL for 10 years.  For the last 5 years, I have been developing Percona Toolkit (formerly “Maatkit”).  Almost 1 year ago, we began developing Percona Cloud Tools (PCT), first in-house, then in private beta, and now in public beta.

Here is the TL;DR:

Percona Cloud Tools is a web service, hosted by Percona.  There is a single cloud tool (a web app) called ”Query Analytics”, based on pt-query-digest, so one could say it’s “continuous slow log analysis through the web, as a service”.  Of course, the web enables us to do more and make things easier. …

How can we bring query to the data?

Baron recently wrote about sending the query to the data looking at distributed systems like Cassandra. I want to take a look at more simple systems like MySQL and see how we’re doing in this space.

It is obvious getting computations as closer to the data as possible is the most efficient as we will likely have less data to work with on the higher level in this case. Internally MySQL starts add optimizations which help in this regard, such as Index Condition Pushdown which allow storage engine to do most rudimentary data filtering improving efficiency.

The more important case though is the Application – Database interaction. Modern applications often have quite complicated logic which might not map to SQL very well. Framework and the practices developers follow can only add to this problem. As results Application may be issuing a …

Amazon RDS with MySQL 5.6 – Configuration Variables

One longstanding complaint I have heard for the past several years, and still hear today, is that Amazon’s Relational Database Service (RDS) does not allow the configuration flexibility as running MySQL in an ec2 instance. While true, this ignores the consistent work that Amazon has done to provide access to the most important configuration variables needed to tune a MySQL instance (after all, how relevant is it for a customer to set bind_address in an RDS instance).

Let’s take a look visually:

MySQL provides 523 options (35 of them NDB specific, so aren’t relevant to RDS), while RDS provides (via the web UI) …

TokuMX is MongoDB on steroids

I am actually quite excited about Tokutek’s release of TokuMX. I think it is going to change the landscape of database systems and it is finally something that made me looking into NoSQL.

Why is TokuMX interesting? A few reasons:

  • It comes with transactions, and all that good stuff that transactions provide: a concurrent access to documents (no more global write-lock in MongoDB); crash recovery; atomicity
  • Performance in IO-bound operations
  • A good compression rate, which is a money-saver if you use SSD/Flash
  • But it is also SSD/Flash life-time friendly, which is double money-saver

So having all these factors it is just a no-brainer if you have a …

Why use encrypted backup with Percona XtraBackup 2.1 for MySQL?

We just released our first alpha of Percona XtraBackup 2.1 for MySQL and with it we included the ability to encrypt backups on the fly (full documentation here). This feature is different than simply piping the backup stream through the openssl or gpg binaries, which is what some people have used in the past. A big benefit of using the built-in encryption is that multiple CPU cores can be used for encryption (with the --encrypt-threads option). You can also combine compression and encryption, each using multiple CPU cores.

One advantage of …
