Attended two Informix Bootcamps last week in Zagreb, Croatia: Informix Performance Tuning Bootcamp and Informix TimeSeries Bootcamp. Although lots of stuff related to performance tuning are already heard of and well known, it was nice to have it all well organized in topics and presented. On the other hand, TimeSeries Bootcamp provided good introduction to this DataBlade and lots of time to do a nicely prepared hands-on lab. Seems like a cool technology, and worth investing your time in exploring it more thoroughly.
If you have opportunity to attend these bootcamps, I definitely recommend it.
