    Abstract: A column-store database engine operates in response to database requests for the update and retrieval of data from within a stable data table and provides for the storage of database tuples within a column-store organized database structure. A positional delta tree data structure is implemented in the memory space of the database engine and is operatively coupled in an update data transfer path between a database engine interface and the stable data table. The positional delta tree data structure includes a differential data storage layer operative to store differential update data values in positionally defined relative reference to database tuples stored by the stable data table.

    Abstract translation: 列存储数据库引擎响应于来自稳定数据表中的数据更新和检索的数据库请求而操作，并且提供在列存储组织的数据库结构中的数据库元组的存储。 位置增量树数据结构在数据库引擎的存储器空间中实现，并且可操作地耦合在数据库引擎接口和稳定数据表之间的更新数据传输路径中。 位置增量树数据结构包括差分数据存储层，其操作以将差分更新数据值存储在由稳定数据表存储的数据库元组的位置定义的相对参考中。

    Abstract: A system and method for just in time compilation for hash table probing are disclosed. In one implementation, the method of using just-in-time compilation is used to combine the stages of hash value computation and initial lookup into a single compound operation. In another implementation, the method of using just-in-time compilation is used to combine the stages of a hash table record and input record checking to detect if these records are equal, and if not, fetching the next possible record in the linked list of the per-bucket records.
