Advanced and Generic Joins
Our data scientist Balázs describes an extension of the join concept. The built-in Join operator only supports equality comparisons, but some problems can be better solved with different kinds of operations, just like in SQL.
His solution is a generic, easily configured script that allows the user to specify an arbitrary join condition. The included example demonstrates an advanced join with a regular expression match. The blog entry is available here in German and English.
