问题描述

ghtorrent-bq 数据非常适合GitHub的快照，但是，它不清楚它何时更新以及如何获得更新的数据

解决方案

（与可以提供帮助），但同时您可以合并两个数据集（查找GHTorrent快照数据，然后添加最新的星星GitHub Archive）：

  #standardSQL 
 SELECT COUNT（DISTINCT登录）c 
 FROM（
 SELECT登录
 FROM（
 SELECT login 
 FROM`ghtorrent-bq。 ght_2017_01_19.watchers` a 
 JOIN`ghtorrent-bq.ght_2017_01_19.projects` b 
 ON a.repo_id = b.id 
 JOIN`ghtorrent-bq.ght_2017_01_19.users` c 
 ON a.user_id = c.id 
 WHERE url ='https://api.github.com/repos/angular/angular'
）
 UNION ALL（
 SELECT actor.login 
 FROM`githubarchive.month.2017 *`
 WHERE repo.name ='angular / angular'
 AND type =WatchEvent
）
）

The ghtorrent-bq data is great to have snapshot of GitHub, however, it is not clear when it is updated and how I could get more up to date data

解决方案

GHTorrent only provides a periodical snapshot of their data on BigQuery, while GitHub Archive updates daily (or even hourly - let me check that).

It would be great to have a more frequent snapshot of GHTorrent (maybe https://twitter.com/gousiosg can help), but in the meantime you can merge both datasets (look for the GHTorrent snapshot data, and then add the latest stars from GitHub Archive):

#standardSQL
SELECT COUNT(DISTINCT login) c
FROM (
  SELECT login
  FROM (
    SELECT login
    FROM `ghtorrent-bq.ght_2017_01_19.watchers` a
    JOIN `ghtorrent-bq.ght_2017_01_19.projects` b
    ON a.repo_id=b.id
    JOIN `ghtorrent-bq.ght_2017_01_19.users` c
    ON a.user_id=c.id
    WHERE url = 'https://api.github.com/repos/angular/angular'
  )
  UNION ALL (
    SELECT actor.login
    FROM `githubarchive.month.2017*` 
    WHERE repo.name='angular/angular'
    AND type = "WatchEvent"
  )
)
