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.

System and method using partial just-in-time compilation to resolve memory access pattern problems in hash table probing

A computer system hosting a column-store database engine is responsive to database requests for the update and retrieval of data from within a stable data table and providing 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.

High-performance database engine implementing a positional delta tree update system

A system and method for improved query processing in a database are provided, where different methods of performing the same task can be adaptively chosen. The system can then adapt to different and changing environments, resulting in improved and more stable performance.

Methods of operating a column-store database engine utilizing a positional delta tree update system

A constant-vector computation system and method are provided that exploit constant-value blocks during data processing in a database. The system and method may be implemented in any data processing system that processes data at a vector or block granularity.

Constant-vector computation system and method that exploits constant-value sequences during data processing

A system and method for buffer management in a database are provided in which a predictive buffer manager may be used. The predictive buffer manager and process may predict when each block in a buffer is going to be used and then manages the buffer based on the prediction.
