TokuDB impacts InnoDB Performance?

TokuDB impacts InnoDB performance

This blog discusses how TokuDB impacts InnoDB performance when the two run in the same environment. You would think MySQL storage engines are fairly independent of each other, even in the same environment. Enabling one, or changing its configuration, logically should have no impact on the performance of other engines (such as InnoDB) when they […]

InnoDB and TokuDB on AWS

 | February 1, 2016 |  Posted In: Benchmarks, InnoDB, TokuDB

In a recent post, Vadim compared the performance of Amazon Aurora and Percona Server on AWS. This time, I am comparing write throughput for InnoDB and TokuDB, using the same workload (sysbench oltp/update/update_non_index) and a similar set-up (r3.xlarge instance, with general purpose ssd, io2000 and io3000 volumes) to his experiments. All the runs used 16 threads for sysbench, and the following […]

Checkpoint strikes back

 | August 3, 2015 |  Posted In: MongoDB, MySQL

In my recent benchmarks for MongoDB, we can see that the two engines WiredTiger and TokuMX struggle from periodical drops in throughput, which is clearly related to a checkpoint interval – and therefore I correspond it to a checkpoint activity. The funny thing is that I thought we solved checkpointing issues in InnoDB once and […]

InnoDB vs TokuDB in LinkBench benchmark

 | July 24, 2015 |  Posted In: Benchmarks, MySQL, Percona Server, TokuDB

Previously I tested Tokutek’s Fractal Trees (TokuMX & TokuMXse) as MongoDB storage engines – today let’s look into the MySQL area. I am going to use modified LinkBench in a heavy IO-load. I compared InnoDB without compression, InnoDB with 8k compression, TokuDB with quicklz compression. Uncompressed datasize is 115GiB, and cachesize is 12GiB for InnoDB […]

Using Cgroups to Limit MySQL and MongoDB memory usage

 | July 1, 2015 |  Posted In: InnoDB, MongoDB, MySQL

Quite often, especially for benchmarks, I am trying to limit available memory for a database server (usually for MySQL, but recently for MongoDB also). This is usually needed to test database performance in scenarios with different memory limits. I have physical servers with the usually high amount of memory (128GB or more), but I am […]
