Bigtable

BigTable 是一種高效能的Google檔案系統(Google File System, GFS)，用於儲存大规模結構化資料，適用於雲端計算。

BigTable 發展於 2004年^[1] 現今已成為 Google 的應用程式, 像是 MapReduce就常透過 BigTable來儲存或更改資料,^[2]至於其他還有 Google Reader,^[3] Google Maps,^[4] Google Book Search, "My Search History", Google Earth, Blogger.com, Google Code hosting, Orkut,^[4] YouTube,^[5] and Gmail.^[6] Google自行發展出特別的巨型資料庫的原因自然是效能的問題.^[7]

BigTable不是传统的關連性資料庫，不支援 JOIN 这样的SQL語法, BigTable更像今日的NoSQL, 优势在于扩展性和性能。
