Read-Only Transactions in Partitioned Replicated Databases

Multiple versions of data are used in database systems to increase concurrency. The higher concurrency results since read-only transactions can be executed without any concurrency control overhead and, therefore, read-only transactions do not interfere ...

This paper presents an efficient scheme for eliminating conflicts between distributed read-only transactions and distributed update transactions, thereby reducing synchronization delays. The scheme makes use of a multiversion mechanism in order to ...
