TAG: a Tiny AGgregation service for ad-hoc sensor networks
TLDR
This work presents the Tiny AGgregation (TAG) service for aggregation in low-power, distributed, wireless environments, and discusses a variety of optimizations for improving the performance and fault tolerance of the basic solution.

TinyDB: an acquisitional query processing system for sensor networks
TLDR
This work evaluates issues in the context of TinyDB, a distributed query processor for smart sensor devices, and shows how acquisitional techniques can provide significant reductions in power consumption on the authors' sensor devices.

A comparison of approaches to large-scale data analysis
TLDR
A benchmark consisting of a collection of tasks that are run on an open source version of MR as well as on two parallel DBMSs shows a dramatic performance difference between the two paradigms.

BlinkDB: queries with bounded errors and bounded response times on very large data
TLDR
BlinkDB allows users to trade-off query accuracy for response time, enabling interactive queries over massive data by running queries on data samples and presenting results annotated with meaningful error bars.

Speedy transactions in multicore in-memory databases
TLDR
A commit protocol based on optimistic concurrency control that provides serializability while avoiding all shared-memory writes for records that were only read, which achieves excellent performance and scalability on modern multicore machines.

TelegraphCQ: Continuous Dataflow Processing for an Uncertain World
TLDR
The next generation Telegraph system, called TelegraphCQ, is focused on meeting the challenges that arise in handling large streams of continuous queries over high-volume, highly-variable data streams and leverages the PostgreSQL open source code base.

Scalable Semantic Web Data Management Using Vertical Partitioning
TLDR
The results show that a vertical partitioned schema achieves similar performance to the property table technique while being much simpler to design, and if a column-oriented DBMS is used instead of a row-oriented database, another order of magnitude performance improvement is observed, with query times dropping from minutes to several seconds.
