Vadim TkachenkoIn this blog post I’ll look at the performance of Percona XtraDB Cluster on AWS using different service instances, and recommend some best practices for maximizing performance. You can use Percona XtraDB Cluster in AWS environments. We often get questions about how best to deploy it, and how to optimize both performance and spend when […]
In this blog post, we’ll look at some of the facets of InnoDB page compression. Somebody recently asked me about the best way to handle JSON data compression in MySQL. I took a quick look at InnoDB page compression and wanted to share my findings. First, the good part. InnoDB page compression is actually really easy to […]
I will be presenting at the ClickHouse MySQL Silicon Valley Meetup on Wednesday, October 25, 2017, at 6:30 PM. ClickHouse is a real-time analytical database system. Even though they’re only celebrating one year as open source software, it has already proved itself ready for the serious workloads. We will talk about ClickHouse in general, some internals […]
In this blog, I’ll use ClickHouse and Tabix to look at a new very large dataset for research. It is hard to come across interesting datasets, especially a big one (and by big I mean one billion rows or more). Before, I’ve used on-time airline performance available from BUREAU OF TRANSPORTATION STATISTICS. Another recent example is NYC […]
In this blog, I’ll look at how to use ClickHouse for parallel log processing. Percona is seen primarily for our expertise in MySQL and MongoDB (at this time), but neither is quite suitable to perform heavy analytical workloads. There is a need to analyze data sets, and a very popular task is crunching log files. Below […]
In this blog post, we’ll look at nested data structures in ClickHouse and how this can be used with PMM to look at queries. Nested structures are not common in Relational Database Management Systems. Usually, it’s just flat tables. Sometimes it would be convenient to store unstructured information in structured databases. We are working to adapt ClickHouse […]
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 […]
In this blog post, we’ll look at how ClickHouse performs in a general analytical workload using the star schema benchmark test. We have mentioned ClickHouse in some recent posts (ClickHouse: New Open Source Columnar Database, Column Store Database Benchmarks: MariaDB ColumnStore vs. Clickhouse vs. Apache Spark), where it showed excellent results. ClickHouse by itself seems […]
In this blog, we’ll look at how to achieve better-than-linear scaling. Scalability is the capability of a system, network or process to handle a growing amount of work, or its potential to be enlarged to accommodate that growth. For example, we consider a system scalable if it is capable of increasing its total output under […]
In our latest release of Percona XtraDB Cluster, we’ve introduced major performance improvements to the MySQLwrite-set replication layer. In this post, we want to show what these improvements look like. For the test, we used the sysbench OLTP_RW, UPDATE_KEY and UPDATE_NOKEY workloads with 100 tables, 4mln rows each, which gives about 100GB of datasize. In all […]
We have been working on bringing out a build of MyRocks with Percona Server for MySQL. MyRocks is a RocksDB-based storage engine. You can find more information about MyRocks here. While there is still a lot of work to do, I want to share an experimental build of Percona Server for MySQL with MyRocks, which […]
In this post, I’ll explain how to run Percona Server for MySQL and Percona Server for MongoDB on Bash on Windows on Ubuntu. We are getting a good number of questions about whether Percona Server (for both MySQL and MongoDB) is available for Windows for evaluation or development purposes. I want to provide a guide to how to […]
In this blog, I’ll go over my thoughts on what we can expect in the world of SQL databases. After reading Baron’s prediction on databases, here: https://www.xaprb.com/blog/defining-moments-in-database-history/ I want to provide my own view on what’s coming up next for SQL databases. I think we live in interesting times, when we can see the beginning of […]
In this blog post, we’ll look at how to run Percona XtraDB Cluster on Windows using Docker. This is a follow-up to my previous post on Percona XtraBackup on Windows. The fact is that with Docker you can now run a variety of software applications on Windows that previously were available only for Linux platforms. We […]
In this blog, we’ll look at running Percona XtraBackup on Windows via a Docker container. The question whether Percona XtraBackup is available for Windows comes up every so often. While we are not planning to provide regular releases for Windows, I decided to share a way to run Percona XtraBackup in a Docker container (especially since […]
This blog post is my overview of Group Replication technology. With Oracle clearly entering the “open source high availability solutions” arena with the release of their brand new Group Replication solution, I believe it is time to review the quality of the first GA (production ready) release. TL;DR: Having examined the technology, it is my […]
In this blog post, we’ll point to a new Docker image for Percona Server for MySQL Group Replication. Our most recent release of Percona Server for MySQL (Percona Server for MySQL 5.7.17) comes with Group Replication plugins. Unfortunately, since this technology is very new, it requires some fairly complicated steps to setup and get running. To help […]
In this post, I’ll point you to MyRocks Docker images with binaries, allowing you to install and play with the software. During the @Scale conference, Facebook announced that MyRocks is mature enough that it has been installed on 5% of Facebook’s MySQL slaves. This has saved 50% of the space on these slaves, which allows them […]
The GA release of ProxySQL 1.2.1 is available. You can get it from https://github.com/sysown/proxysql/releases. There are also Docker images for Release 1.2.1: https://hub.docker.com/r/percona/proxysql/. ProxySQL is a high-performance proxy, currently for MySQL and its forks (like Percona Server and MariaDB). It acts as an intermediary for client requests seeking resources from the database. ProxySQL was created for DBAs by […]
In this blog post, we’ll discuss how a small innodb_page_size can create a performance boost for SSD. In my previous post Testing Samsung storage in tpcc-mysql benchmark of Percona Server I compared different Samsung devices. Most solid state drives (SSDs) use 4KiB as an internal page size, and the InnoDB default page size is 16KiB. I wondered […]
