摘要： In column domain dictionary compression, column values in one or more columns are tokenized by a single dictionary. The domain of the dictionary is the entire set of columns. A dictionary may not only map a token to a tokenized value, but also to a count (“token count”) of the number of occurrences of the token and corresponding tokenized value in the dictionary's domain. Such information may be used to compute queries on the base table.

摘要： Clients are permitted to directly attach to a client server system. An oplog management system tracks changes as clients make the changes to control structures of the direct connection client server system. The Oplogging system stores changes in oplogs. Then, if a client fails, the Oplogging system can repair the control structures, either by undoing the changes made by the client, or else completing the changes in place of the client; depending upon principles defined.

摘要翻译： 允许客户端直接连接到客户端服务器系统。 当客户端进行更改以控制直接连接客户端服务器系统的结构时，Oplog管理系统跟踪更改。 Oplogging系统存储oplogs中的更改。 然后，如果客户端失败，则Oplogging系统可以通过撤销客户端所做的更改来修复控制结构，也可以修改客户端的更改; 取决于所定义的原则。
