  • Observations on the hashicorp/raft library, and notes on RDBMS

    June 20, 2017

    The hashicorp/raft library is a Go library to provide consensus via Raft protocol implementation. It is the underlying library behind Hashicorp's Consul. I've had the opportunity to work with this library a couple projects, namely freno and orchestrator. Here are a few observations on working with this library: TL;DR on Raft: a group communication protocol; […]

  • Practical Orchestrator, BoF, GitHub and other talks at Percona Live 2017

    April 19, 2017

    Next week I will be presenting Practical Orchestrator at Percona Live, Santa Clara. As opposed to previous orchestrator talks I gave, and which were either high level or algorithmic talks, Practical Orchestrator will be, well... practical. The objective for this talk is that attendees leave the classroom with a good grasp of orchestrator's powers, and […]

  • "MySQL High Availability tools" followup, the missing piece: orchestrator

    April 6, 2017

    I read with interest MySQL High Availability tools - Comparing MHA, MRM and ClusterControl by SeveralNines. I thought there was a missing piece in the comparison: orchestrator, and that as result the comparion was missing scope and context. I'd like to add my thoughts on topics addressed in the post. I'm by no means an […]

  • orchestrator Puppet module now available

    February 1, 2017

    We have just open sourced and published an orchestrator puppet module. This module is authored by Tom Krouper of GitHub's database infrastructure team, and is what we use internally at GitHub for deploying orchestrator.

  • Orchestrator progress

    December 23, 2015

    This comes mostly to reassure, having moved into GitHub: orchestrator development continues. I will have the privilege of working on this open source solution in GitHub.

    This post sums up some of my work on MySQL resilience and high availability at Booking.com by presenting the current state of automated master and intermediate master recoveries via Pseudo-GTID & Orchestrator.

  • Orchestrator & Pseudo-GTID for binlog reader failover

    November 19, 2015

    One of our internal apps at Booking.com audits changes to our tables on various clusters. We used to use tungsten replicator, but have since migrated onto our own solution. We have a binlog reader (uses open-replicator) running on a slave. It expects Row Based Replication, hence our slave runs with log-slave-updates, binlog-format='ROW', to translate from the […]

  • Thoughts on MaxScale automated failover (and Orchestrator)

    November 18, 2015

    Having attended a talk (as part of the MariaDB Developer Meeting in Amsterdam) about recent developments of MaxScale in executing automated failovers, here are some (late) observations of mine. I will begin by noting that the project is stated to be pre-production, and so of course none of the below are complaints, but rather food […]

  • Orchestrator visual cheatsheet, TL;DR the "smart" way

    September 2, 2015

    Orchestrator is really growing. And the amount of users (DBAs, sys admins) using it is growing. Which gives me a lot of immediate feedback in the form of "Look, there's just too many options to move slaves around! Which ones should we use?" TL;DR look at the two visualized commands below They are enough The "smart" commands to […]
