The federated optimizer also allows the T-ETL solution to be adaptive, as the best join strategy and link ordering may change as the characteristics of the data in the job change.
联邦优化器还使t - ETL解决方案更具有可适应性,因为当作业中数据特征发生变化时,最佳连接策略和链接顺序也可能随之变化。
However, it is a relatively simple task to convert StockCheck into a T-ETL schema by only converting a small part of the job; that is, the join between LINEITEM and STOCK.
但是,将StockCheck转换成t - ETL模式则相当简单,只需转换作业中的一小部分,即LINEITEM与STOCK之间的连接。
Glen: Christopher and I always go for hamburgers and fries after the game. We "re crazy about fast food. Why don" t you and Yunbo join us?
格伦:比赛结束后克里斯托弗和我总是去吃汉堡包和炸薯条。我们特别喜欢吃快餐。你和云波跟我们一起去吧?
