Takes a json object, and considers each field to be a separate datapoint’s data. It removes all elements for which its first argument returns true (filters).

filter allows you to remove values from an object based upon a condition. For example:

  "a": 45,
  "b": 23,
  "c": -3

Running the transform filter($<0) on the above datapoint, will give an output:

  "a": 45,
  "b": 23

The transform “filtered” out all values that are less than 0.


The main use case of the filter transform is in combination with the map transform, when map returns too many values. For example, if looking at browsing history, you might have visited thousands of websites, but only be interested in the ones you visited more than 30 times:

map(domain,count) | filter($<=30)
