A filter is a JSON object indicating which rows of data should be included in
the computation for a query. It’s essentially the equivalent of the WHERE
clause in SQL. Apache Druid supports the following types of filters.
+**Note**

+Filters are commonly applied on dimensions, but can be applied on metrics as
well.
Review comment:
In my head, i was thinking filtering on aggregates, like filtering on
metrics in a groupby. Sure, adding a link to those would be useful here.
Separately, does anyone know if we started supporting filtering metrics
since a particular release version which should be specified here ?
