Parallelized redo-only logging and recovery for highly available main memory database systems |
December 4, 2007 |
| A parallel logging and recovery scheme for highly available main-memory database systems is presented. A preferred embodiment called parallel redo-only logging ("PROL") combines physical logging and selective replay of redo-only log records. During physical logging, log records are g |

Cache-conscious concurrency control scheme for database systems |
November 6, 2007 |
| An optimistic, latch-free index traversal ("OLFIT") concurrency control scheme is disclosed for an index structure for managing a database system. In each node of an index tree, the OLFIT scheme maintains a latch, a version number, and a link to the next node at the same level of the |

Compression scheme for improving cache behavior in database systems |
October 16, 2007 |
| A cache-conscious version of the R-tree, called the CR-tree, is disclosed. To pack more entries in a node, the CR-tree compresses MBR keys, which occupy substantial part of the index data. It first represents the coordinates of an MBR key relatively to the lower left corner of its pa |
