Efficiently Reclaiming Space in a Log Structured Store

Autor: Lomet, David, Luo, Chen

A log structured store uses a single write I/O for a number of diverse and non-contiguous pages within a large buffer instead of using a write I/O for each page separately. This requires that pages be relocated on every write, because pages are never

Recent work on "learned indexes" has changed the way we look at the decades-old field of DBMS indexing. The key idea is that indexes can be thought of as "models" that predict the position of a key in a dataset. Indexes can, thus, be learned. The ori

Implementing Performance Competitive Logical Recovery

Autor: Lomet, David, Tzoumas, Kostas, Zwilling, Michael

Publikováno v: Proceedings of the VLDB Endowment (PVLDB), Vol. 4, No. 7, pp. 430-439 (2011)

New hardware platforms, e.g. cloud, multi-core, etc., have led to a reconsideration of database system architecture. Our Deuteronomy project separates transactional functionality from data management functionality, enabling a flexible response to exp

Unbundling Transaction Services in the Cloud

Autor: Lomet, David, Fekete, Alan, Weikum, Gerhard, Zwilling, Mike

The traditional architecture for a DBMS engine has the recovery, concurrency control and access method code tightly bound together in a storage engine for records. We propose a different approach, where the storage engine is factored into two layers
