Transaction management across data stores

Speculative Transaction Processing in Geo-Replicated Data Stores

This work presents STR, a geo-distributed, partially replicated transactional data store, which leverages on novel speculative techniques to mask the inter-replica synchronization latency. The theoretical foundations on top of which we built STR is a novel consistency criterion, which we call SPeculative Snapshot Isolation (SPSI). SPSI extends the well-known Snapshot Isolation semantics in an i...

Mobile data and transaction management

Mobile computing paradigm has emerged due to advances in wireless or cellular networking technology. This rapidly expanding technology poses many challenging research problems in the area of mobile database systems. The mobile users can access information independent of their physical location through wireless connections. However, accessing and manipulating information without restricting user...

Transaction Management on Replicated Data

Scalable Transactions across Heterogeneous NoSQL Key-Value Data Stores

Many cloud systems provide data stores with limited features, especially they may not provide transactions, or else restrict transactions to a single item. We propose a approach that gives multi-item transactions across heterogeneous data stores, using only a minimal set of features from each store such as single item consistency, conditional update, and the ability to include extra metadata wi...

Transaction Aware Vertical Partitioning of Database (tavpd) for Responsive Oltp Applications in Cloud Data Stores

Online transaction Processing (OLTP) applications are business applications which are characterized by high-frequency short lived data transactions. In cloud domain, applications are expected to be highly responsive and low cost with optimized levels of consistency. Cloud data stores rely on an appropriate data partitioning scheme to achieve promising levels of responsiveness and scalability. T...
