Dremel is a scalable, interactive ad hoc query system for analysis of read-only nested data. By combining multilevel execution trees and columnar data layout, it is capable of running aggregation queries over trillion-row tables in seconds. The system scales to thousands of CPUs and petabytes of data, and has thousands of users at Google. In this paper, we(More)
Spanner is Google’s scalable, multi-version, globallydistributed, and synchronously-replicated database. It is the first system to distribute data at global scale and support externally-consistent distributed transactions. This paper describes how Spanner is structured, its feature set, the rationale underlying various design decisions, and a novel time API(More)
Mesa is a highly scalable analytic data warehousing system that stores critical measurement data related to Google’s Internet advertising business. Mesa is designed to satisfy a complex and challenging set of user and systems requirements, including near real-time data ingestion and queryability, as well as high availability, reliability, fault tolerance,(More)
Spanner is a globally-distributed data management system that backs hundreds of mission-critical services at Google. Spanner is built on ideas from both the systems and database communities. The first Spanner paper published at OSDI'12 focused on the systems aspects such as scalability, automatic sharding, fault tolerance, consistent replication, external(More)

In the Big Data group, MapReduce has been seen as one of the key empowering methodologies for taking care of ceaselessly expanding requests on figuring assets forced by Big Datasets yet at the same time numerous issues arrive with MapReduce keeping in mind the end goal to handle a much more extensive cluster of employments, combination into Hadoop's native(More)
In the given paper the effective simulation technique of quartz oscillators the in time domain with use of general purpose EDA software (PSPICE, MicroCAP, etc) is offered. The main idea is reception of averaged on the first harmonic parameters of nonlinear active part of self-oscillating circuit with the help of widespread programs of circuit simulation,(More)
