在reddit評論數據集中 - 哪些帖子上傳到1000評論最快？

Question

從https://www.reddit.com/r/datasets/comments/3icas8/reddit_july_comments_are_now_available/cuiahh9?context=3

哪些意見提升速度最快？ （哪些提交在N秒內達到了第1,000條評論 - 按N升序排序）。基於評論數量加速提交提交。 （我假設新聞報道是最快的）。

Answer 1

讓我們的排名爲每個帖子按時間發佈的評論，看看在第1和第1000個，採取由兩個和訂單之間的時間差：

SELECT link_id, FIRST(IF(rank=1000,created_utc,null)) - FIRST(IF(rank=1,created_utc,null)) thousand 
FROM (
    SELECT link_id, created_utc, RANK() OVER(PARTITION BY link_id ORDER BY created_utc) rank 
    FROM [fh-bigquery:reddit_comments.2015_07] 
) 
WHERE rank=1000 OR rank=1 
GROUP BY link_id 
HAVING NOT thousand IS null 
ORDER BY thousand
