UI¶
OPAL¶
group_by()
a path within an object
value¶
The group_by()
function already allows grouping results by the value of a specified field. Now you can group by the value of a specific element in an object-typed field. For example, group by the values in tags.clusterUid
rather than all of the possible values in the tags
field. For details, see the examples in the group_by()
documentation.
Using a timestamp
field as part of a primary key¶
The set_primary_key()
verb now supports using a time field as part of a primary key. While this is not a typical use, it is occasionally useful if you need to generate resources that contain only one interval each.
Note
set_primary_key
is a low-level operation that requires some care in use. In most cases, you will more easily accomplish your goal using make_resource
, update_resource
, timechart
, or make_event
.
