On Cost-Optimal Merge of Two Intransitive Sorted Sequences
The problem of merging two intransitive sorted sequences (that is, to generate a sorted total order without the transitive property) is considered. A cost-optimal parallel merging...

Fault-Tolerant Parallel Applications with Dynamic Parallel Schedules
Commodity computer clusters are often composed of hundreds of computing nodes. These generally off-the-shelf systems are not designed for high reliability. Node failures therefore...

Warm cache costing: a feedback optimization technique for buffer pool aware costing
Most modern RDBMS depend on the query processing optimizer’s cost model to choose the best execution plan for a given query. Since the physical IO (PIO) is a costly operation to...

A Heuristic Approach for Optimization of Path Expressions
Abstract. The object-oriented database management systems store references to objects (implicit joins, precomputed joins), and use path expressions in query languages. One way of e...
