Don’t wait, submit a talk for Percona Live Europe 2018 to be held in Frankfurt 5-7 November 2018. The call for proposals is ending soon, there is a committee being created, and it is a great conference to speak at, with a new city to boot!

Releases

• A big release, MySQL 8.0.12, with INSTANT ADD COLUMN support, BLOB optimisations, changes around replication, the query rewrite plugin and lots more. Naturally this also means the connectors get bumped up to the 8.0.12, including a nice new …

The main focus of a previous blog post was the performance of MyRocks when using fast SSD devices. However, I figured that MyRocks would be beneficial for use in cloud workloads, where storage is either slow or expensive.

In that earlier post, we demonstrated the benefits of MyRocks, especially for heavy IO workloads. Meanwhile, Mark wrote in his blog that the CPU overhead in MyRocks might be significant for CPU-bound workloads, but this should not be the issue for IO-bound workloads.

In the cloud the cost of resources is a major consideration. Let’s review the annual cost for the processing and storage …

OSCON happened last week and was incredible. It is true there was less of a database focus, and a lot more topics covered. In fact, you’d have found it hard to find database content. There was plenty of interesting content around AI/ML, cloud, SRE, blockchain and more. As a speaker, the 40-minute sessions that included a Q and A session was quite compact (I felt it was a little too short, and many speakers sped up towards the end). I guess it will make for more blog content.

The conference’s open source ethos is still extremely strong, and the keynotes exemplified that. It was not just the 20th anniversary of OSCON, but also the 20th anniversary of the …

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 …

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 …

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 …

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) …

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 …
