LOAD DATA INFILE is one transaction. Infobright is transactional even over LOAD DATA, eg that needs to be committed, either automatically or explicitly, and can be rolled back as well. Easy to do when there can be only one client writing… Anyway, sync behavior isn’t really relevant in an ADMBS workload loading and querying thousands, if not millions of rows at a time. I did some followup testing as well, and that 2000 rows/sec figure seems about right after all — it’s the 200 columns that do it. Loading speed is in proportion to number of columns, and I’ve been dealing with 10-50 column tables myself..

What’s Infobright’s sync behaviour? If it forces sync after each transaction (as is the default setting in InnoDB), then that could be rather slow on an Amazon machine if the transactions are small or implicit; Amazon’s service doesn’t deal with high IO rates too well.

Some scaling observations on Infobright…

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…

Thanks for the tip! That is what I was looking for, but I was out of my familiar terrain.

Baron, the “simple” way to find out MonetDB’s version is either by looking at merovingian’s logfile (the server issues a startup notice with its version), or by running mserver5 –version.

By the way, in reply to an earlier comment/question about Infobright, I get

mysql> SELECT sum(c19), sum(c89), sum(c129), count(*) FROM t WHERE c11< 5;
+----------+----------+-----------+----------+

Because saying the version number crosses the line from a quick test to a lengthy test? But seriously,

./mysqld Ver 5.1.14-log for pc-linux-gnu on i686 (build number (revision)=IB_3.2_GA_5316(ice))
./mysqld-ubuntu Ver 5.0.75-0ubuntu10.2 for debian-linux-gnu on i486 ((Ubuntu))

MonetDB doesn’t seem to have such a simple way to find out, but dpkg says:

ii monetdb5-server 5.14.2-20090924 MonetDB database server version 5

Why you don’t put the version used of each software? that’s is very important!! there are differences between infobright 3.1.1 and 3.2 (ICE vs IEE), MySQL 4.1 vs 5.0 vs 5.1, for example.
