Some time ago, I published the article on AWS Aurora Benchmarking (AWS Aurora Benchmarking – Blast or Splash?), in which I analyzed the behavior of different solutions using synchronous replication in AWS environment. This blog follows up with some of the comments and suggestions I received regarding that post from the community and Amazon engineers. […]

Benchmark MongoDB with sysbench

In this blog post, we’ll discuss how to benchmark MongoDB with sysbench. In an earlier post, I mentioned our use of sysbench-mongodb (via this fork) to run benchmarks of MongoDB servers. I now want to share our work extending sysbench to make it work with MongoDB. If you’re not familiar with sysbench, it’s a great project developed […]

Is MySQL’s innodb_file_per_table slowing you down?

 | February 24, 2015 |  Posted In: Benchmarks, InnoDB, MySQL, Percona MySQL Consulting, Percona Server

MySQL’s innodb_file_per_table is a wonderful thing – most of the time. Having every table use its own .ibd file allows you to easily reclaim space when dropping or truncating tables. But in some use cases, it may cause significant performance issues. Many of you in the audience are responsible for running automated tests on your […]

Testing TokuDB’s Group Commit Algorithm Improvement

 | December 23, 2014 |  Posted In: Tokutek, TokuView

The MySQL 5.6 Release has introduced some changes to how two phase commit works and is managed.  In particular, the commit phase of transactions to the binary log is now serialized and this behavior is something we identified fairly immediately.  We implement a group commit algorithm that needed to be altered so that TokuDB’s group […]

Scaling TokuDB Performance with Binlog Group Commit

 | December 17, 2014 |  Posted In: Tokutek, TokuView

TokuDB offers high throughput for write intensive applications, and the throughput scales with the number of concurrent clients.  However, when the binary log is turned on, TokuDB 7.5.2 throughput suffers.  The throughput scaling problem is caused by a poor interaction between the binary log group commit algorithm in MySQL 5.6 and the way TokuDB commits […]

Fast Updates : Coming Soon in TokuMX v2.0

 | September 29, 2014 |  Posted In: Tokutek, TokuView

Coming in TokuMX v2.0 is a feature we’re calling “Fast Updates”. Fast updates permit certain update operations to bypass the read-modify-write behavior that most databases require (including MongoDB and the current release of TokuMX). In this blog I’ll cover how Fast Updates work by describing a simple schema and workload, plus I’ll measure the performance […]

 | September 23, 2014 |  Posted In: Tokutek, TokuView
