The London Hadoop User Group gets to hear Exasol’s view Last night I gave a talk to a Meetup of the Hadoop User Group in London about SQL-on-Hadoop, and my theory that it would never replace specialist SQL engines like Exasol. I’ve enjoyed attending these informal meetups over the past year or so – they’re […]
How the “Exasol Beast” is eating up the TPC-H benchmark and scaring the living daylights out of our competitors. We have recently completed a new attempt at the TPC-H benchmark and the results are quite startling, even by our high standards from three years ago when we set the bar already way beyond the reach […]
Exasol can cope with unstructured data using User Defined Functions “Structured data” is the kind of data that you could work with in a (sufficiently large) spreadsheet. There are fixed fields within a record and there’s a data model which defines what fields of data will be stored and how that data will be stored […]
Exasol is truly easy-to-use and self-tuning – not like certain other databases I could mention. This is one of my favourite pictures – at first sight it looks like a wonderful idea to have such flexibility but then you wonder – if your car is starting to slide into a wall at over 200 mph […]
There are four basic features that contribute to Exasol’s speed, which I call the “four degrees of awesome” Exactly how do you make the fastest database in the world? A few years ago I was looking at new technologies for a consultancy company. During the course of this I came across Exasol’s TPC-H benchmark figures. […]
Exasol holds the TPC-H benchmark record for 100 GB, 300 GB, 1 TB, 3 TB and 10 TB. There’s no real debate about who is the “Fastest Man on Earth”. It’s currently Usain Bolt – we’ve seen him run the 100 Metres faster than anyone else, so there’s surely no argument. The 100 Metres is […]
Geospatial functions: Adventures in Space as well as in Time I have put together another one of my (legendary?) videos on the subject of Geospatial functions. One of the problems with our product being so well-known for speed is that people often forget that it is good for more than just supernaturally fast table joins […]
Exasol made the fastest database in the world – but just how critical is database speed? I was asked by a journalist recently whether speed really matters with a database and it stopped me in my tracks. I found it hard to imagine that anyone would even ask such a question. Good databases are fast […]
With Exasol 5 you can now write User-Defined Functions in Java – a new video shows you how. Exasol 5 now supports the use of Java as a programming language for User-Defined functions and I’ve produced a video describing the process of developing a Java UDF here. In version 4, you could have used Lua, […]
Exasol 5.0 now allows you to run Java code in-memory and parallel. Some people just plain don’t like SQL. OK, maybe they don’t dislike it – it’s just that it’s totally not the way they see the world. The Hadoop guys and gals, for example, live and breathe Java. To them, life is a class […]
