Market-like distributed optimization tackles some of these barriers, especially if only limited data exchange is possible between the constituent production plants. However, distributed optimization algorithms typically need many iterations, which hinders their practical application. In this contribution, we ...

s implementation of Spanner. In contrast to Google Spanner, CockroachDB runs on commodity hardware, which lacks the high-precision clocks that help Spanner to scale consistent transactions. Instead, CockroachDB uses different, though similar,algorithms and techniquesto provide distributed transactions like ...

If PolyBase encounters an unexpected error during the distributed query optimization phase, and tries to create a memory dump to capture the state of the system, you may notice that the dump creation fails. In ...
they used local datasets. However, when the datasets are distributed and provided by third party services, range query optimization becomes more challenging. Handling distributed datasets in a performance efficient way requires addressing the issues related to replications [5],...

Query processing over data stream has attracted much attention in real-time applications. While many efforts have been paid for query processing of data streams in distributed environment, no previous study focused on multiple-query optimization. To address this problem, we propose EsperDist, a ...
