gh-ost 1.0.42 released: JSON support, optimizations

gh-ost 1.0.42 is released and available for download.

JSON

MySQL 5.7's JSON data type is now supported.

There is a soft-limitation, that your JSON may not be part of your PRIMARY KEY. Currently this isn't even supported by MySQL anyhow.

Performance

Two noteworthy changes are:

  • Client side prepared statements reduce network traffic and round trips to the server.
  • Range query iteration avoids creating temporary tables and filesorting.

We're not running benchmarks at this time to observe performance gains.

5.7

More tests validating 5.7 compatibility (at this time GitHub runs MySQL 5.7 in production).

Ongoing

Many other changes included.

We are …

On Open Source Databases. Interview with Peter Zaitsev

“To be competitive with non-open-source cloud deployment options, open source databases need to invest in “ease-of-use.” There is no tolerance for complexity in many development teams as we move to “ops-less” deployment models.” –Peter Zaitsev

I have interviewed Peter Zaitsev, Co-Founder and CEO of Percona.
In this interview, Peter talks about the Open Source Databases market; the Cloud; the scalability challenges at Facebook; compares MySQL, MariaDB, and MongoDB; and presents Percona’s contribution to the MySQL and MongoDB ecosystems.

Q1. What are the main technical challenges in obtaining application scaling?

Peter Zaitsev: When it comes to scaling, there are different types. There is a Facebook/Google/Alibaba/Amazon scale: these …

orchestrator/raft: Pre-Release 3.0

orchestrator 3.0 Pre-Release is now available. Most notable are Raft consensus, SQLite backend support, orchestrator-client no-binary-required client script.

TL;DR

You may now set up high availability for orchestrator via raft consensus, without need to set up high availability for orchestrator's backend MySQL servers (such as Galera/InnoDB Cluster). In fact, you can run a orchestrator/raft setup using embedded SQLite backend DB. Read on.

orchestrator still supports the existing shared backend DB paradigm; nothing dramatic changes if you upgrade to 3.0 and do not configure raft.

Blog Poll: What Operating System Do You Run Your Development Database On?

In this post, we’ll use a blog poll to find out what operating system you use to run your development database servers.

In our last blog poll, we looked at what OS you use for your production database. Now we would like to see what you use for your development database.

As databases grow to meet more challenges and expanding application demands, they must try and get the maximum amount of performance out of available resources. How they work with an operating system can affect many variables, and help or hinder performance. The operating system you use for your database can impact consumable choices (such as hardware and memory). The operating system you use can also impact your choice of database engine as well (or vice versa).

When new projects, new applications or services or testing new architecture …

ClickHouse: One Year!

In this blog, we’ll look at ClickHouse on its one year anniversary.

It’s been a year already since the Yandex team released ClickHouse as open source software. I’ve had an interest in this project from the very start, as I didn’t think there was an open source analytical database that could compete with industry leaders like Vertica (for example).

This was an exciting year for ClickHouse early adopters. Let’s look at what it accomplished so far.

ClickHouse initially generated interest due to the Yandex name – the most popular search engine in Russia. It wasn’t long before jaw-dropping responses popped up: guys, this thing is crazy fast! Many early adopters who tried ClickHouse were really impressed.

Fast doesn’t mean convenient …

Blog Poll: What Operating System Do You Run Your Production Database On?

In this post, we’ll use a blog poll to find out what operating system you use to run your production database servers.

As databases grow to meet more challenges and expanding application demands, they must try and get the maximum amount of performance out of available resources. How they work with an operating system can affect many variables, and help or hinder performance. The operating system you use for your database can impact consumable choices (such as hardware and memory). The operation system you use can also impact your choice of database engine as well (or vice versa).

Please let us know what operating system you use to run your database. For this poll, we’re asking which operating system you use to actually run your production database server (not the base operating system).

If you’re running …
