过期的分配查询

数据与报告

一旦开始分配主题，不可避免地会出现分配过时的情况。

我们着手找出它们。

因此，这里是查询，以防它对其他人有用。
有 2 个子查询需要自定义：

  • SonarSourcers（别问我为什么不直接用“staff”）
  • teams
-- 目标：显示过时分配，
--    其中过时是指自分配以来 7 天，
--    并且没有来自 SonarSourcers 的公开活动/“常规”帖子
--    并且 SonarSourcer 的帖子不是最后一个帖子


WITH

-- 查找所有已分配的主题
assigned_topics AS (
    SELECT a.topic_id
        , assigned_to_type
        , assigned_to_id

在我们的模型中，我们为团队分配成员（或子团队）。

让我们看看团队在初步分类和重新分配方面的表现：

-- goal: find time from assignment to group 
--    to re-assignment to sub-team / SonarSourcer
--    目标：查找从分配到组到重新分配到子团队/SonarSourcer的时间

-- [params]
-- date :start_date = 2022-10-01
--    [params]
--    日期 :start_date = 2022-10-01

WITH

-- find last group assignment in the thread
group_assignment AS (
    SELECT max(p.post_number) AS assignment_post, p.topic_id --, max(p.created_at) as d
    FROM posts p
    WHERE p.action_code in ('assigned_group', 'assigned_group_to_post')
        AND p.created_at >= :start_date
    GROUP BY p.topic_id
),
-- 查找线程中上次的组分配
--    查找线程中上次的组分配

-- get the details of the assignment post
group_assignment_deets AS (
    SELECT p.id as post_id, p.created_at as d, p.topic_id, pcf.value as who
    FROM posts p
    JOIN group_assignment ga on ga.topic_id=p.topic_id
        AND p.post_number = ga.assignment_post
    JOIN post_custom_fields pcf ON pcf.post_id = p.id
    WHERE pcf.name = 'action_code_who'

),
-- 获取分配帖子的详细信息

-- find the re-assignment that came after the group assignment
next_assignment AS (
    SELECT min(p.post_number) AS assignment_post, p.topic_id --, min(p.created_at) as d
    FROM posts p
    JOIN group_assignment ga on ga.topic_id=p.topic_id
    WHERE p.action_code in ('assigned', 'assigned_to_post', 'reassigned_group', 'reassigned') 
        AND p.post_number > ga.assignment_post
    GROUP BY p.topic_id
),
-- 查找组分配之后发生的重新分配

-- get the details of the assignment post
next_assignment_deets AS (
    SELECT p.id as post_id, p.created_at as d, p.topic_id, pcf.value as who
    FROM posts p
    JOIN next_assignment na ON na.topic_id=p.topic_id 
        AND p.post_number = na.assignment_post
    JOIN post_custom_fields pcf ON pcf.post_id = p.id

-- 获取分配帖子的详细信息

-- calculate days to reassignment for each thread
days_per_team AS (
    SELECT gad.who as team
        , extract(epoch from (nad.d - gad.d)/86400) as days
    FROM group_assignment_deets gad
    JOIN next_assignment_deets nad using(topic_id)
)

-- 为每个线程计算重新分配的天数
--    为每个线程计算重新分配的天数

SELECT 
    team as "Team"
    , count(*) as "Thread count"
    , round(avg(days)::numeric,2) as "Avg days to reassignment"
    , round(max(days)::numeric,2) as "Max"
    , round(min(days)::numeric,6) as "Min"
FROM days_per_team
GROUP BY team
ORDER BY "Thread count" desc

请注意，此查询没有任何可自定义的内容；它应该对所有人“都能正常工作”。
