코호트

무엇을 하는지 또는 무엇인지로 정의된 사람들의 집합: 모든 코호트는 이름과 정의이며, 정의는 쓰인 대로 읽히는 절입니다. 이 이벤트를 며칠 안에 몇 번 했다, 또는 이 속성이 이 값이다. 빈 정의는 아무도 선택하지 않으며, 이는 의도된 것입니다.

The library

Each card is one cohort: its name, whether it is active, how many people it currently selects and how fresh that answer is. A cohort whose clauses count behaviour over history is swept on a schedule and says when it was last evaluated, or that it never has been; one defined purely by current attributes is live and carries no timestamp, because a timestamp would imply a staleness it does not have. The toolbar narrows by search, kind and state, and deleting asks first, warning that analyses filtered by the cohort stop being filtered by it.

세 번째 종류는 정적입니다: 정의가 아니라 사람들의 고정된 목록입니다. 분석 워크벤치에서 결과로부터 Save로 남기거나, New cohort 대화상자에 붙여 넣은 목록으로 만듭니다. 한 번도 다시 평가되지 않으므로, 훑는 코호트가 타임스탬프를 다는 자리에 이 카드는 한 번도 없음, 의도된 것이라고 적습니다. 열면 정의가 아니라 목록 자체가 펼쳐집니다. 몇 명을 담고 있는지, 목록이 어디에서 왔는지, Add people, 그리고 각 행 옆의 제거입니다.

The definition editor

A cohort opened to its definition

Opening a card unfolds its definition in place: behavioural clauses (did an event at least so many times within so many days, with the project's own event names suggested) and state clauses (an attribute compared to a value). A cohort is named first and defined after, and an empty definition selects nobody rather than everybody, which the open row says in as many words. Opening a second card does not close the first, so two definitions can be compared side by side without losing edits.

New cohort는 이름을 먼저 묻고 그다음 Membership을 묻습니다. 두 종류는 만드는 방식이 다르고, 코호트에 이름을 붙이는 대화상자가 바로 종류가 정해지는 자리이기 때문입니다. Defined by rules는 위에서 설명한 정의를 줍니다. A fixed list of people은 distinct id를 적는 칸을 드러냅니다. 한 줄에 하나씩, 한 번에 10,000개까지이며 나중에 더 넣을 수 있습니다. 그렇게 만든 코호트는 사람들을 안에 담은 채 태어나고 곧바로 활성입니다.

Where cohorts are used

A cohort scopes a question in the Analytics workbench, targets a campaign in the Inbox, and gates workflow triggers on the Workflows screen. The same set of people, wherever the set is needed.

Where this meets the API

The concept behind the screen is the People and cohorts pillar; the people being selected are the People directory. On the wire: the library is the cohorts query, cohort reads one and cohortMemberCount counts its people; editing is createCohort, updateCohort, setCohortActive and deleteCohort; a static cohort is born by createStaticCohort from a pasted list or by createCohortFromResult from a result, its list moves by addCohortMembers and removeCohortMembers, and cohortMembers reads it back a page at a time (GraphQL reference).

The definition as JSON

A rules cohort's definition is one JSON object, the definition argument of createCohort and updateCohort and the definition field of the MCP tools prodantix.cohorts.create and prodantix.cohorts.update. It holds clauses, a list of at most 32, and a person is a member when every clause matches. An empty list selects nobody. A field the shape does not name is refused, so read an existing cohort with cohort or prodantix.cohorts.get before changing one.

JSON
{
  "clauses": [
    { "kind": "state", "condition": { "attribute": "plan", "op": "eq", "value": "pro" } },
    { "kind": "state", "condition": { "attribute": "country", "op": "in", "value": ["DE", "AT", "CH"] } },
    { "kind": "behavioural", "event": "purchase", "atLeast": 3, "withinDays": 30 }
  ]
}

State clauses

{ "kind": "state", "condition": { ... } }. The condition names an attribute, one of the person's properties or distinct_id, an op and, for most operators, a value. The operators are eq, neq, in, not_in, contains, gt, gte, lt, lte, is_set, is_not_set. eq, neq and contains compare as text; gt, gte, lt and lte compare as numbers; in and not_in take a list of values; is_set and is_not_set take none, and a property that is empty text counts as not set. A cohort made only of state clauses is live: a person joins or leaves the moment an event changes the property. The two cohort operators of flag targeting, in_cohort and not_in_cohort, are refused here: a cohort cannot be defined by another cohort.

Behavioural clauses

{ "kind": "behavioural", "event": "purchase", "atLeast": 3, "withinDays": 30 }: the person did the event at least atLeast times in the last withinDays days. Both are whole numbers, and a person counts only once they did the event at all, so an atLeast of 0 reads as 1. One behavioural clause makes the cohort swept: its members are worked out on a schedule rather than as events land, and the cohort says when it last was.

Static cohorts

A static cohort's definition is { "kind": "static", "clauses": [] }: its members are a list somebody wrote, not rules. Given to createCohort it makes an empty list; createStaticCohort or prodantix.cohorts.create_static makes one holding its people, and createCohortFromResult makes one from a result. An update cannot turn a rules cohort into a static one or back; make a new cohort of the kind you want.
