In our recent report on the data warehousing market we speculated that there would soon be a change in the number of vendors operating in what is a crowded market. We were anticipating that the number of vendors would go down, rather than up, but - in the short term at least - we have been proved wrong, as two new open source analytical databases emerged this week.

First came the formation of Dynamo Business Intelligence Corp, (aka Dynamo BI), a new commercially supported distribution, and sponsor, of LucidDB. Then came the launch of InfiniDB Community Edition, a new open source analytic database based on MySQL from Calpont.

Open source business intelligence and data warehousing are on the rise!

If you kept up with the MySQL Performance Blog, you might have noticed a number of posts comparing the open source analytical databases Infobright, LucidDB, and MonetDB. LucidDB …

The future of MySQL. The SCO Group terminates Darl McBride. And more.

The future of MySQL
Monty Widenius urged Oracle to give up on MySQL in order to land Sun while Richard Stallman, Knowledge Ecology International (KEI) and the Open Rights Group sent a letter to the EC urging it to block Oracle’s acquisition of MySQL. All of which prompted Florian Mueller, who it should be noted is working with Widenius as part of his campaign, to claim that there is growing public opposition to Oracle owning Sun’s MySQL.

Meanwhile The VAR Guy reported on rumours that …

A couple of days ago, Baron Schwartz posted some simple load and select benchmarking of MyISAM, Infobright and MonetDB, which Vadim Tkachenko followed up with a more realistic dataset and interesting figures where MonetDB beat Infobright in most queries.

Used to the parallel IEE loader, I was surprised by the apparent slow loading speed of Baron's benchmark and decided to try and replicate it. I installed Infobright 3.2 on my laptop (see, this is very unscientific) and wrote a simple perl script to generate and load an arbitrarily large data set resembling Baron's description. I'm not going to post my exact numbers, because this installation is severely …

Accidentally me and Baron played with InfoBright (see http://www.mysqlperformanceblog.com/2009/09/29/quick-comparison-of-myisam-infobright-and-monetdb/) this week. And following Baron's example I also run the same load against MonetDB. Reading comments to Baron's post I tied to load the same data to LucidDB, but I was not successful in this.

I tried to analyze a bigger dataset and I took public available data
http://www.transtats.bts.gov/DL_SelectFields.asp?Table_ID=236&DB_Short_Name=On-Time about USA domestic flights with information about flight length and delays.

The data is available from 1988 to 2009 in chunks per month, so I downloaded 252 files (for 1988-2008 years) with …

Recently I was doing a little work for a client who has MyISAM tables with many columns (the same one Peter wrote about recently). The client's performance is suffering in part because of the number of columns, which is over 200. The queries are generally pretty simple (sums of columns), but they're ad-hoc (can access any columns) and it seems tailor-made for a column-oriented database.

I decided it was time to actually give Infobright a try. They have an open-source community edition, which is crippled but not enough to matter for this test. The "Knowledge Grid" architecture seems ideal for the types of queries the client runs. But hey, why not also try MonetDB, another open-source column-oriented database I've been …

I’ve been investigating a few different storage engines for MySQL lately, and something I’ve noticed is that they all list what they support, but they generally don’t say what they don’t support. For example, Infobright’s documentation shows a list of every data type supported. What’s missing? Hmm, I don’t see BLOB, BIT, ENUM, SET… it’s kind of hard to tell. The same thing is true of the list of functions that are optimized inside Infobright’s own code instead of at the server layer. I can see what’s optimized, but I can’t see whether FUNC_WHATEVER() is optimized without scanning the page — and there’s no list of un-optimized functions.

I don’t mean to pick on Infobright. I’ve recently looked at another third-party storage engine and they did exactly the same thing. It’s just that the docs I saw weren’t public as …
