主题：【原创】对SNS架构的非典型性批评 -- 邓侃
昨天看到一则消息，有个startup自己利用mapreduce原理开发了个支持SQL的datawarehouse，估计这次可以赢得许多DBA们的好感了，不过与你前面所提的SQL overhead问题似乎是有百害而无一利，呵呵。
文中也提到Apache opensource主持的Hadoop与微软的科研院项目Dryad， 其中Hadoop更是被yahoo与NY Times采用多年了:
Aster and Greenplum aren't the only ones taking advantage of MapReduce. Apache has also developed an open source version of MapReduce known as Hadoop.Yahoo (NSDQ: YHOO) uses Hadoop for Web search and advertising, and The New York Times has used Hadoop in combination with Amazon (NSDQ: AMZN) Web services to transform millions of old articles that were each in several disparate scanned TIFF images into PDF format. Microsoft (NSDQ: MSFT) Research has developed a similar parallel computing framework known as Dryad.
