One-shot Garbage Collection for In-memory OLTP through Temporality-aware Version Storage
Anastasia Ailamaki, Periklis Chrysogelos, Angelos Christos Anadiotis, Syed Mohammad Aunn Raza
Most modern in-memory online transaction processing (OLTP) engines rely on multi-version concurrency control (MVCC) to provide data consistency guarantees in the presence of conflicting data accesses. MVCC improves concurrency by generating a new version o ...
ACM2023Determining an optimum quantity of interleaved instruction streams of defined coroutines
Anastasia Ailamaki, Georgios Psaropoulos
A method for optimizing memory access for database operations is provided. The method may include performing a first database operation by at least executing a first instruction stream associated with the first database operation. The first database opera ...
2023Robustness Against Read Committed: A Free Transactional Lunch
Transaction processing is a central part of most database applications. While serializability remains the gold standard for desirable transactional semantics, many database systems offer improved transaction throughput at the expense of introducing potenti ...
