The MySQL Track (and More) at Percona Live 2019

This year we’re having a different concept for Percona Live conferences, which started at Percona Live Europe 2018 last fall. This is an approach practiced by many other organizations by having separate track for MySQL®, MongoDB®, MariaDB®, or PostgreSQL and more.

So we formed several mini-committees to make sure that the submissions to each of the tracks received the right level of attention from the right kind …

We are pleased to announce the launch of PMM 2.0.0-alpha1, Percona’s first Alpha release of our long-awaited PMM 2 project!

Live MySQL Slave Rebuild with Percona Toolkit

Recently, we had an edge case where a MySQL slave went out-of-sync but it couldn’t be rebuilt from scratch. The slave was acting as a master server to some applications and it had data was being written to it. It was a design error, and this is not recommended, but it happened. So how do you synchronize the data in this circumstance? This blog post describes the steps taken to recover from this situation. The tools used to recover the slave were pt-slave-restartpt-table-checksum, pt-table-sync and mysqldiff.

Scenario

To illustrate this …

A New Dashboard to Monitor Memory Usage in the PMM plugin!

While the PMM team works hard on our PMM 2.0 release, we have been working on a few things in the background which we’d like to show off !  In particular we have developed a new dashboard that displays metrics related to memory usage on Linux systems. The dashboard leverages information collected by node_exporter. The graphs take advantage of  /proc filesystem files, specifically:

  • meminfo: Provides information about distribution and utilization of memory. This varies by architecture and compile options.
  • vmstat: Provides information about block IO and CPU activity in addition to memory.
