Github Big Query 存档中缺少数据？

Question

Big Query 上的 Github 存档中缺少数据？

使用 BigQuery's tables from the Github Archive, and running a query on pull-requests for the typelevel/cats repo，2016 年 1 月 1 日之前没有条目，尽管实际回购显示 activity 从 2015 年 1 月 28 日开始。

查询如下。想检查一下，看看这是不是我的错误或误解，或者是否有一些回购协议在 BQ 表中仅部分可用。

SELECT 
  DATE(created_at) AS date, repo.name, count(*) AS num_PR
FROM
  (TABLE_DATE_RANGE([githubarchive:day.],
     TIMESTAMP('2014-09-26'),
     TIMESTAMP('2016-09-26')
  ))
WHERE
  type = 'PullRequestEvent'
  AND JSON_EXTRACT(payload, '$.action') = '\"opened\"'
  AND repo.name IN ('typelevel/cats')
GROUP BY date, repo.name
ORDER BY date DESC

Answer 1

此存储库更改了名称，但 ID 保持不变：

SELECT repo.name, MIN(created_at) since, MAX(created_at) until
FROM (TABLE_DATE_RANGE([githubarchive:day.],
       TIMESTAMP('2015-01-01'),
       TIMESTAMP('2016-10-01')
    ))
WHERE repo.id = 29986727
GROUP BY 1
ORDER BY 1


repo_name       since                   until    
non/cats        2015-01-28 20:26:49     2016-01-30 20:30:41      
typelevel/cats  2016-01-30 20:32:30     2016-09-30 16:47:03
