Minimizing coordination, or blocking communication between concurrently executing
operations, is key to maximizing scalability, availability, and high performance in database …

Next generation high-performance RDMA-capable networks will require a fundamental
rethinking of the design and architecture of modern distributed DBMSs. These systems are …

State machine replication (SMR) is a well-known technique able to provide fault-tolerance.
SMR consists of sequencing client requests and executing them against replicas in the …

Snapshot isolation (SI) is a widely used consistency model for transaction processing,
implemented by most major databases and some of transactional memory systems …

Replication is a key mechanism to achieve scalability and fault-tolerance in databases. Its
importance has recently been further increased because of the role it plays in achieving …

A database supporting multiple versions of records may use the versions to support queries
of the past or to increase concurrency by enabling reads and writes to be concurrent. We …

(57) ABSTRACT A system and method of performing Snapshot isolation in distributed
databases. Each node stores local snapshot infor mation that enforces Snapshot isolation …

Snapshot isolation (SI) is supported by most commercial databases and is widely used by
applications. However, checking SI today---given a set of transactions, checking if they obey …

State-machine replication is a well-established approach to fault tolerance. The idea is to
replicate a service on multiple servers so that it remains available despite the failure of one …

Modern database systems employ Snapshot Isolation to implement concurrency control and
isolationbecause it promises superior query performance compared to lock-based …
