Abstract
Cloud computing is still a rather new field, which is not yet entirely defined. As a result, many interesting research
problems exist, often combining different research areas such as databases, distributed systems or operating systems. This paper
focuses data storage Consistency Rationing as a new transaction paradigm, which not only allows defining the consistency
guarantees on the data instead of at transaction level, but also allows for automatically switching consistency guarantees at runtime. We present a number of techniques that make the system dynamically adapt the consistency level by monitoring the data
and/or gathering temporal statistics of the data. The last part of the paper is concerned with XQuery as a unified programming
model for the cloud and, in particular, the missing capabilities of XQuery for windowing and continuous queries. XQuery is able to
run on all layers of the application stack, is highly optimizable and parallelizable, and is able to work with structured and semi
structured data.
