Shard-Query 2.0 performance on the SSB with InnoDB on Tokutek’s MariaDB distribution

Scaling up a workload to many cores on a single host

Here are results for Shard-Query 2.0 Beta 1* on the Star Schema Benchmark at scale factor 10.  In the comparison below the “single threaded” response times for InnoDB are the response times reported in my previous test which did not use Shard-Query.

Shard-Query configuration

Shard-Query has been configured to use a single host.  The Shard-Query configuration repository is stored on the host.  Gearman is also running on the host, as are the Gearman workers.  In short, only one host is involved in the testing.

The …

Scalable Star Schema Benchmark (SSB) Join Metrics

We ran a quick scalability test of Calpont join behavior across using a Star Schema Benchmark data set at a scale factor of 1000. The Star Schema Benchmark transforms a TPC-H / DBT-3 data to a more standardized data warehouse star schema data model, and the 1000 scale factor includes 6 billion rows in the primary fact table. Information on the star schema bench (SSB) can be found at .

-- Note that these queries are run without any tuning or indices created for these joins or filters.
-- Basically, this is just 1) Create tables (without index or …

Kickfire: stream-processing SQL queries

Some of you have noticed Kickfire, a new sponsor at this year’s MySQL Conference and Expo. Like Keith Murphy, I have been involved with them for a while now. This article explains the basics of how their technology is different from the current state of the art in complex queries on large amounts of data.

Kickfire is developing a MySQL appliance that combines a pluggable storage engine (for MySQL 5.1) with a new kind of chip. On the surface, the storage engine is not that revolutionary: it is a column-store engine with data compression and some other techniques to reduce disk I/O, which is kind of par for the course in data warehousing today. The chip is the really exciting part of the technology.

The simplest description of their chip is that it …
