Event Ruler · Event Ruler is a Java library that allows matching Rules to Events. An event is a list of fields, which may be given as name/value pairs or as a JSON object. A rule associates event field names with lists of possible values. There are two reasons to use Ruler: 1/ It's fast; the time it takes to match Events doesn't depend on the number of Rules. 2/ Customers like the JSON "query language" for expressing rules.
