MarkLogic has long had the ability to spawn tasks, consisting of a module, a set of variables and some options. Those tasks go into the task queue and get worked off by the configured number of threads. A new feature…
I’ve started a couple posts lately, only to find them more complex than expected. So to get myself back on the board, tonight you get a pretty simple one, based on an error one of my colleagues encountered recently. Suppose we…
Today I get to give you a sneak peak into a feature that's not yet officially present, but you'll find if you know where to look: XQuery-level integration with ImageMagick! In this post I demonstrate automatically scaling down large images for CurioVault.com.
