Latest Patents

Kostas Tzoumas holds a patent for "Logical recovery with unbundled transaction services." This patent application relates to enhanced logical recovery techniques for redo recovery operations of a system with an unbundled storage engine. The techniques can be implemented by utilizing an enhanced logical recovery approach in which a dirty page table (DPT) is constructed based on information logged during normal execution. The unbundled storage engine can include a transaction component (TC) that is architecturally independent of a data component (DC). These techniques can enhance redo recovery operations by mitigating the resources needed to determine whether previously executed operations sent from the TC to the DC are to be repeated in response to a recovery-initiating event. This can include using the DPT to avoid fetching every data page corresponding to every previously executed operation received by the DC during recovery and/or pre-fetching data pages and/or index pages that correspond to PIDs in the DPT.
