This Week in Data with Colin Charles 44: MongoDB 4.0 and Facebook MyRocks

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

There have been two big pieces of news this week: the release of MongoDB 4.0 and the fact that Facebook has migrated the Messenger backend over to MyRocks.

MongoDB 4.0 is stable, with support for multi-document ACID transactions. I quite like the engineering chalk and talks videos on the transactions page. There are also improvements to help manage your MongoDB workloads in a Kubernetes cluster. MongoDB Atlas supports global clusters (geographically distributed databases, low latency writes, and data placement controls for regulatory …

On InnoDB Data Compression in MySQL

Another story that I've prepared back in April for my meeting with one of customers in London was a "compression story". We spent a lot of time on it in several support issues in the past, with only limited success.

In case of InnoDB tables, there are actually two ways to compress data (besides relying on filesystem compression or compressing individual columns at server or application side). Historically the first one was introduced by the Barracuda InnoDB file format and ROW_FORMAT=COMPRESSED it supported. Notable number of related bugs were reported with time, and it may be not that easy to identify them all (you can find current list of bugs tagged with "compression" …

This Week in Data with Colin Charles 41: Reflecting on GitHub’s Contribution to Open Source Database

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

Some big news out from Microsoft about their acquisition of GitHub for $7.5 billion. GitHub hosts many projects, including from the MySQL ecosystem, but maybe more interesting is that their DBA team is awesome, give great talks, and are generally prolific writers. Some of the cool tools the MySQL world has gotten thanks to the excellent team include (but are not limited to): ccql, gh-ost for triggerless online schema migrations, and Orchestrator which is a GUI-based High Availability and …

A friendly comparison of InnoDB and MyRocks Performance

In this blog post, we have multiple OLTP performance benchmarking scenarios using sysbench 1.0.14 on InnoDB and MyRocks. InnoDB and MyRocks (RocksDB with MySQL) are definitely not to supplement each other, They actually compliment well with respective advantages, Let me quickly explain how InnoDB and MyRocks can benefit you when used wisely, Again this blog post is not to show who (InnoDB or MyRocks) is better ? We regularly benchmark both of these storage engines before recommending to our customers on what is best suited for their database infrastructure operations ? so we would like to share our thoughts on this post.

How InnoDB and MyRocks are different ?

  • MyRocks supports only READ-COMMITTED isolation level, There is no REPEATABLE-READ isolation level like InnoDB so no gap locking like InnoDB, We have written detailed blog on InnoDB transaction isolation levels …

Benchmarking InnoDB and MyRocks Performance using Sysbench

We are are an vendor neutral and independent open source database technologies consulting, support and remote DBA services provider with several customers using MySQL GA, MySQL Enterprise, InnoDB/XtraDB, Percona Server, MariaDB, MyRocks and ClickHouse. The customers continue doing business with us for being an technology / vendor agnostic company. We spend considerable amount of time doing research on open source database technologies, Often customers ask us about the performance comparison between InnoDB and MyRocks so we decided to write this post to compare performance between InnoDB (MySQL 8.0) and MyRocks (MariaDB 10.3.7) using Sysbench 1.0.14:

Software Infrastructure we have used for this benchmarking : 

MySQL 8.0 / InnoDB  (no custom tuning done for performance)

[root@localhost sysbench]# cat /etc/redhat-release 
CentOS Linux release 7.3.1611 (Core) …

This Week in Data with Colin Charles 39: a valuable time spent at rootconf.in

Join Percona Chief Evangelist Colin Charles as he covers happenings, gives pointers and provides musings on the open source database community.

rootconf.in 2018 just ended, and it was very enjoyable to be in Bangalore for the conference. The audience was large, the conversations were great, and overall I think this is a rather important conference if you’re into the “DevOps” movement (or are a sysadmin!). From the data store world, Oracle MySQL was a sponsor, as was MyDBOPS (blog), and Elastic. There were plenty more, including Digital Ocean/GoJek/Walmart Labs — many MySQL users.

I took a handful of pictures with people, and here are some of the MyDBOPS team and myself.  They have over 20 …

ClickHouse Meetup in Salt Lake City

Join Percona CTO Vadim Tkachenko at the Cloud Native Utah meetup in Salt Lake City on Tuesday, May 8, 2018, for an Intro to ClickHouse.

Next week, I’ll be switching from MyRocks performance testing and present an introduction to ClickHouse to the Cloud Native Utah meetup.

Interestingly enough, even though it is totally different from OLTP engines, ClickHouse uses a MergeTree engine. MergeTree engines have a lot of similarities with Log Structured Merge Tree (which is what is used by MyRocks / RocksDB). This the structure is optimized to run on huge datasets / low memory scenarios.

A Look at MyRocks Performance

In this blog post, I’ll look at MyRocks performance through some benchmark testing.

As the MyRocks storage engine (based on the RocksDB key-value store http://rocksdb.org ) is now available as part of Percona Server for MySQL 5.7, I wanted to take a look at how it performs on a relatively high-end server and SSD storage. I wanted to check how it performs for different amounts of available memory for the given database size. This is similar to the benchmark I published a while ago for InnoDB (https://www.percona.com/blog/2010/04/08/fast-ssd-or-more-memory/).

In this case, I plan to use a sysbench-tpcc benchmark ( …
