Spanner's concurrency control [PDF]
ACM SIGACT News, 2013 The Spanner project reports that one can build practical large-scale systems that combine strong semantics with geo-distribution. In this review manuscript, we provide insight on how Spanner's concurrency control provides both read-only transactions which avoid locking data, and strong consistency.

Modular Synchronization in Multiversion Databases: Version Control and Concurrency Control [PDF]
, 1989 In this paper we propose a version control mechanism that enhances the modularity and extensibility of multiversion concurrency control algorithms. We decouple the multiversion algorithms into two components: version control and concurrency control. This

Infinite Resources for Optimistic Concurrency Control
NetCompute@SIGCOMM, 2018 Optimistic concurrency control (OCC) is inefficient for high-contention workloads. When concurrent transactions conflict, an OCC system wastes CPU resources verifying transactions, only to abort them.

An efficient locking model for concurrency control in OODBS
Data Science Journal, 2006 When several transactions execute concurrently in a database, the isolation property may no longer be preserved. It is necessary for the system to control the interaction among the concurrent transactions.

Critical Care, 2020 Background Conceptually, the “control of gut overgrowth” (COGO) is key in mediating prevention against infection with Gram-negative bacilli by topical antibiotic prophylaxis, a common constituent of selective digestive decontamination (SDD) regimens ...

The Logical Timestamp Skew Anomaly in Event-Replicated Transaction Schedulers
IEEE Access, 2021 To sidestep reasoning about the complex effects of concurrent execution, many system designers have conveniently embraced strict serializability on the strength of its claims, support from commercial and open-source database communities and ubiquitous ...

Low overhead concurrency control for partitioned main memory databases [PDF]
, 2010 Database partitioning is a technique for improving the performance of distributed OLTP databases, since "single partition" transactions that access data on one partition do not need coordination with other partitions.

TicToc: Time Traveling Optimistic Concurrency Control
SIGMOD Conference, 2016 Concurrency control for on-line transaction processing (OLTP) database management systems (DBMSs) is a nasty game. Achieving higher performance on emerging many-core systems is difficult.
